Sara Auld

Sara Auld  Sara Auld, MD, MSCR
  Assistant Professor of Medicine
 

My research interests are focused around the global TB and HIV epidemics. I have extensive experience in the clinical epidemiology of TB, drug-resistant TB, and TB/HIV coinfection. More recently, I have also begun to explore various aspects of lung health in TB infection, including lung immunology and pulmonary impairment during and after TB infection. I would be happy to meet with trainees about potential projects and explore any interests in these areas.

Nancy A. Collop, MD
Professor of Medicine and Neurology
Director, Emory Sleep Center
Director, Sleep Medicine Fellowship

I came to Emory in 2010 from Johns Hopkins, where I was director of the Johns Hopkins Hospital Sleep Laboratory. I am the director of the Emory Sleep Center, which is an independent cost center and part of Emory Healthcare and Emory University. The Emory Sleep Center moved to Executive Park in February 2015. The Emory Sleep Center has 9 faculty members, and includes 9 sleep laboratory bedrooms, home sleep apnea testing and has its own durable medical equipment program. In 2012, we initiated our sleep medicine fellowship program which has 3 fellows per year.

My area of scholarly interest is in diagnosing and treatment of sleep disorders with a special interest in sleep disordered breathing.  I am interested in new technologies to diagnose and monitor sleep and sleep disorders. My other passion is to continue to enhance our sleep medicine fellowship program to attract the best and brightest residents and fellows to our program, particularly those with academic interests.

Sushma CribbsSushma K. Cribbs, MD, MSc
Associate Professor of Medicine
Associate Program Director, Pulmonary and Critical Care Medicine Fellowship
Staff Physician, Atlanta VA Medical Center

After completing residency and fellowship at Emory University, I joined the faculty at Emory in 2009.  After joining the faculty, I was primarily based at Grady Memorial Hospital where I conducted clinical research and attending on the Pulmonary Consult Service and Medical Intensive Care Unit. I obtained a NIH Clinical Research Loan Repayment grant at the end of fellowship and maintained consistent funding until 2013, when I moved to the Atlanta VA. In 2011, I was awarded a KL2 grant and completed a Masters of Science and Clinical Research through Emory Rollins School of Public Health with a focus on clinical-translational research on the HIV-lung, and investigating mechanistic pathways by which HIV impairs lung host immunity.  I am currently a staff physician at the Atlanta VA, where I attend on Pulmonary Consults and the MICU services. I have continued investigations in the field of HIV lung disease through several clinical trials which have now expanded to other areas of interesting including metabolomics, lung microbiome, Mycobacterium Tuberculosis, and other chronic lung diseases such as chronic obstructive lung disease (COPD).  These projects have broad implications for our understanding of how we can limit the consequences of HIV on the lung, and decrease the lung-specific morbidity and mortality for individuals living with HIV despite adherence to anti-retroviral therapy. 

I am also the Associate Program Director for the Pulmonary & Critical Care Medicine Fellowship Program and as such am very involved in the teaching and mentoring of our fellows. I have also mentored undergraduate, graduate and post-graduate trainees at Emory University both in clinical and scientific arenas.  In addition, I currently participate and Chair a number of committees both in the Department of Medicine, the School of Medicine and in national and regional scientific societies such as the American Thoracic Society and the Southern Society of Clinical Investigation.

Assistant Professor of Medicine
Pulmonary and Critical Care Medicine Fellowship

I completed a fellowship in Pulmonary and Critical Care Medicine at Emory University and joined the faculty in 2011. I currently work at the Atlanta Veterans Affairs Medical Center, where I conduct basic and translational research in pulmonary hypertension (PH). My research examines mechanisms involved in vascular smooth muscle cell proliferation in PH. Specifically I study the role of MicroRNA-21 in the regulation of proliferative signaling pathways in the pulmonary vasculature and examine peroxisome proliferator activated receptor gamma (PPAR) g agonists as potential therapies in experimental models of PH.

I am actively involved with fellowship education and chair the Career Development Committee (CDC) and the Critical Care Ultrasound Committee. I am the Medical Director for Respiratory Therapy at the Atlanta VA. Additionally, I have a strong clinical interest in PH and give a yearly lecture to the first year medical students during the pulmonary block. I also participate in MS1 small group study sessions and journal critiques. I enjoy bedside and small group teaching opportunities with Emory residents and Pulmonary and Critical Care fellows on medical ICU and pulmonary consultation services.

Charles GrodzinCharles J. Grodzin, MD
Assistant Professor of Medicine
Pulmonary, Critical Care, Allergy and Sleep Medicine

 I came to Emory in July 2014.  I have a strong background in general pulmonary medicine and attend clinical services at Emory University Hospital Midtown in the outpatient clinic as well as the pulmonary medical consult service and in the medical 71 ICU.  I am the current medical director of the Respiratory Care Department.  I am a member of the EUHM Pulmonary Embolism Response Team specifically handling Pulmonary Embolism consultations and developing a pulmonary embolism clinic .  I am also a member of multiple quality committees at EUHM.

Into my third full year of my academic career, I am pleased to continue to find enjoyment and satisfaction in sharing my pulmonary and critical care experience with medical students, residents and fellows as we share complex clinical scenarios.  I continue to enjoy honing my skills in the educational spotlight both clinically at the bedside and in more traditional didactic settings via lecture or interactive board review style presentations and the creation of new and exciting patient care opportunities.  For me it is a joy to share my career experiences and spend time with those in training.  In addition, I feel energized by the opportunity to participate in clinical research that affects directly the way we practice on a daily basis.  I look to expand my clinical horizons further as opportunities arise.

At this point, I am available to work with students, residents and fellows in the development of teaching and clinical research projects.  My goals are to add to the knowledge base, bring therapy to the bedside and share findings for use for the greater medical good.  I would love to hear fresh ideas for clinical investigation, novel project or to work with students or trainees to develop projects that are based on their particular interests.

David M. Guidot, MD

David GuidotDavid M. Guidot, MD
Jeffrey R. Pine Chaired Professor of Medicine
Director, Division of Pulmonary, Allergy, Critical Care & Sleep Medicine

I joined the faculty at Emory University as an assistant professor in 1995 following four years of fellowship training and three years on the faculty at the University of Colorado. I had no meaningful research training prior to my fellowship but dedicated three years to laboratory-based research as a fellow and it has been a major facet of my professional activity ever since. My early research focused on basic mechanisms of oxidative stress and has evolved over the years into two related areas; specifically, the effects of chronic alcohol abuse and HIV on lung health. I direct basic laboratory projects in the Whitehead Biomedical Research Building as well as clinical translational projects at the Atlanta VA and Grady. I remain active as a clinician and teaching attending physician as I love clinical medicine and, at least for me, I believe that I am a better clinician because of the intellectual rigor required to do research. Conversely, my research is always in a clinical context because of my active medical practice.

In my twenty years at Emory my greatest passion has been mentoring students, residents and fellows in both clinical medicine and in biomedical research. I have mentored more than twenty post-doctoral fellows (including both MD and PhD trainees) and many more residents and students. As a co-director of a training grant from the NIH, this mentoring includes having minority medical students from Morehouse each summer. In parallel, I have mentored Emory medical students through the Discovery Phase program and literally dozens of medical residents have performed research electives with me. Over the years I have lost count of how many have presented at regional or national meetings, but it must be fifty or more.

For students and residents doing short-term research experiences I focus on instilling a sense of how medical research progresses; specifically, how to ask and answer important questions. Although there is always an element of learning some investigative techniques, the focus is on the intellectual approach and the excitement of pursuing new (and often unexpected) findings. Trainees working with me and my collaborators can work on projects anywhere along the research spectrum, from cell culture to animal models to clinical trials. I know first-hand the value of a positive research experience with mentors who taught me to `think and question¿ and not just `learn techniques¿. My greatest thrill is when a student, resident or fellow gets excited about their research project and presents it at a meeting and/or helps publish the work as a co-author. Although many of my trainees are now actively pursuing academic careers as physician-scientists, many are in clinical academic positions or private practice. I consider all of them to be great successes.

Recent students and residents I mentored:

  • Nnamdi Azih ¿ current Morehouse medical student
  • Eric Kerchberger ¿ Emory medical student and now a resident in emergency medicine at Ohio State
  • Thomas Middour ¿ Emory medical student and now a medicine resident at Tulane
  • Mohita Singh ¿ Emory medical student and now a medicine resident at Baylor

Andre Holder, MD, MSc

Andre HolderAndre Holder, MD, MSc
Assistant Professor of Medicine
Division of Pulmonary, Critical Care, Allergy and Sleep Medicine

Dr. Holder came to Emory in 2014 to begin his career as clinician scientist faculty. After finishing a combined emergency medicine and internal medicine residency in 2009, he completed a Masters of Science in Clinical Research Methodology at Albert Einstein College of Medicine in New York. His research interest are prediction and management of sepsis progression.

During his clinical fellowship in critical care medicine, he did an NIH T32 research fellowship at the University of Pittsburgh. His focus at that time was broadened to hemodynamic monitoring and management of critical illness in general. He performed animal studies in their cardiopulmonary lab using dynamic complex physiologic features as markers for disease progression in a hemorrhage model.

Dr. Holder's current research at Emory focuses on understanding the progression of inflammatory diseases that cause critical illness, with a specific emphasis back on sepsis pathophysiology. Through collaborations with colleagues in the Department of Biomedical Informatics, he employs advanced data-driven techniques such as nonlinear modeling and machine learning approaches to predict the trajectory of complex syndromes like sepsis. His main research focus is proving whether temporal trends in physiologic and laboratory biomarkers, and complex measures of physiologic variability can predict sepsis-related organ dysfunction, cardiovascular collapse (shock), and death. Other research and clinical interests include cardiopulmonary resuscitation, and appropriate use of hemodynamic monitoring and cardiopulmonary interaction in critical illness.

Assistant Professor of Medicine

Division of Pulmonary, Allergy, Critical Care & Sleep Medicine

Director, Emory Adult Cystic Fibrosis Center

Over the course of my combined internal medicine and pediatrics residency training I developed a particular interest and experience in chronic childhood illnesses, especially cystic fibrosis (CF).  I was mentored by Dr. Irena Petrache and explored the role of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) dysfunction in pulmonary endothelial cell barrier integrity.  Following pursuit of fellowship research training in adult pulmonary and critical care medicine I continued to sharpen hypothesis-driven research design.  I trained in the laboratory of Dr. Nael McCarty, director of Emory+Childrens’ Center for Cystic Fibrosis and Airways Disease Research, under the direct mentorship of Dr. Nael McCarty and Dr. Jason Hansen.  Our research focused on innate immunity within the CF lung environment in the setting of CF-related diabetes (CFRD).  Specifically, our focus has been the development and characterization of a murine model of CFRD and exploring the mechanisms of CFRD’s impact on lung function (immune cell activity and redox signaling in particular).  I continue to collaborate with researchers within Emory+Childrens’ Center for Cystic Fibrosis and Airways Disease Research on mechanisms of CF lung dysfunction as well as clinical outcomes. 

My clinical interests is with CF and lung transplantation.  I am the current medical director for the adult CF program at Emory University.  I also serve as the associate director for the CF@lanta Research and Development Program (RDP) Clinical and Translational Core.  Additionally, I serve as a sitting member for the CF@lanta RDP and the CF@lanta CF Scholars steering committees.  My research interests include assessing objective measures of transition readiness in CF, experimental model systems for CF, CFRD lung disease and CF-specific lung transplant outcomes.

Section Chief - Pulmonary, Allergy, Critical Care and Sleep Medicine - Emory Saint Joseph's Hospital

I started my Emory career in May 2016. I am primarily based at Emory Saint Joseph’s hospital but also have clinics at the Emory Sleep Center (12 EP). The primary focus of my research and scholarly activities has been related to the health outcomes of sleep disordered breathing. I specialize in the statistical techniques of meta-analysis, from the simple direct pair-wise meta-analysis to the most complicated network comparative meta-analyses utilizing both Bayesian and Frequentist methodologies. In my brief academic tenure, I have always welcomed and encouraged residents and fellows in learning the statistics of pairwise and network comparative meta-analysis.

Dean Jones, PhD

Dean JonesDean P. Jones, PhD
Professor of Medicine
Director, Clinical Biomarkers Laboratory

Dean Jones is a Professor in the Department of Medicine (Pulmonary Division) with secondary appointments in Biochemistry and Pediatrics at Emory University, Atlanta, GA. He received a Ph.D in Medical Biochemistry from Oregon Health Sciences Univ., Portland, in 1976. He studied nutritional biochemistry at Cornell University and molecular toxicology at the Karolinska Institute as a post-doctoral fellow.  He joined Emory University as an Assistant Professor of Biochemistry in 1979, was subsequently promoted to Associate Professor in 1985 and Professor of Biochemistry in 1990. He became Professor of Medicine and Director of the Clinical Biomarkers Laboratory in 2003.  He is the Integrated Health Sciences Facility Core Director of the NIEHS-supported HERCULES Exposome Research Center and directs metabolomics cores for NIH-funded programs in Children’s Health Exposure Analysis Resource, Red Blood Cell Stability for Transfusion and the Malaria Host-Pathogen Interaction Center.  His research career has included studies of mitochondrial mechanisms of toxicity, redox systems biology, oxidative stress and antioxidant systems, compartmentation of metabolism and high-resolution metabolomics.  He currently is focused on applications of ultra-high resolution mass spectrometry for precision medicine, with a long-term goal to use this as a foundation to sequence the exposome.  These methods allow measurement of thousands of low abundance metabolites, including those derived from the innate metabolism, environment, diet, drugs and microbiome.  He has recently focused on low-level environmental exposures, such as dietary cadmium, which can impact onset and progression of chronic diseases, and has active NIH-supported research programs on the metabolomics of cardiovascular, lung, eye, neurodegenerative and infectious diseases and aging.  He has extensive collaborations to study diverse populations and disease processes.

Recent trainees he mentored

  • Douglas Walker, PhD candidate studying use of high-resolution metabolomics for biomonitoring environmental exposures and linking exposures to health outcomes
  • Ken Liu, PhD candidate studying pharmacometabolomics of adverse drug reactions
  • Joshua Chandler, PhD, Post-doctoral fellow studying integrated omics of inflammation-derived oxidants in lung cells and in vivo
  • Jolyn Fernandez, PhD, Post-doctoral fellow studying mitochondrial oxidative stress induced by manganese and developing integrated models of redox proteomics, metabolomics and transcriptomics
  • Xin Hu, PhD,  Post-doctoral fellow studying integrated omics of low-dose environmental cadmium toxicity specifically related to pro inflammatory and profibrotic signaling in the lung

Potential Projects

Many laboratory projects are possible, but a better training structure would probably involve collaboration with Young-Mi Go, PhD, Shuzhao Li, PhD, and/or a clinical scientist using our –omics analytical capabilities to address highly relevant clinical questions.  This can be done for almost any of the relevant clinical aspects of the Division, I.e., Pulmonary, Allergy, Critical Care and Sleep Medicine.  The main limitation is that the time frame to initiate and complete a clinical protocol usually makes it impractical to do this in its entirety as a Fellow.  Hence, we would want to take advantage of ongoing studies, sample repositories and existing data.  Given the history of research in the Division and the existing collaborations and interactions with clinical scientists at other institutions, this mostly requires initiative to develop a workable plan.

Jordan Kempker, MD, MSc

Jordan KempkerJordan A. Kempker, MD, MSc
Assistant Professor of Medicine

In 2015 I joined Emory faculty after completing my residency and fellowship training here.  During my fellowship training I completed a Masters of Science and Clinical Research through Emory Rollins School of Public Health and my research interests are in intersections of health services research and data science in the topics of sepsis and acute respiratory distress syndrome.  I have mentored three Emory School of Medicine Discovery students and worked with several fellows helping with their research projects. 

Trainees who wish to work with me will be involved with managing and analyzing large healthcare databases and it is important to have some background in computer science, particularly in the SAS or R languages. Those seeking training in the MSCR program will achieve the sufficient background knowledge and skills for this.  Even for trainees who do not work primarily with me, I am happy to serve in a limited role as a consultant to meet a few times and review your project’s study design, data management procedures, and overall goals for feasibly creating scientific output in fellowship.  For those trainees with any interest at all in the MSCR, I’d also encourage you to set up a meeting with me to discuss the commitments, expectations, and other features of the program.

Michael Koval, PhD

Michael KovalMichael Koval, PhD
Professor of Medicine and Cell Biology
Associate Division Director for Research

 
I have a long standing interest and expertise in studying cell membranes, with a particular emphasis in understanding the molecular basis for formation and remodeling of intercellular junctions.  I received my Ph.D. in Cell Biology from Johns Hopkins University and was a Postdoctoral Fellow at Washington University.  From there I became a faculty member in the Department of Physiology at the University of Pennsylvania with a joint appointment at the Institute for Environmental Medicine.  About a decade ago I joined the Department of Medicine and Emory Alcohol and Lung Biology Center at Emory University.  I also have a joint appointment in the Department of Cell Biology.
A major research direction in my lab is to understand how tight junctions regulate the pulmonary air/liquid barrier.  We use molecular and cell biological approaches to define roles for several tight junction proteins (claudins, occludin, ZO-1, ZO-2) in normal lung barrier function and in pathologic conditions such as acute respiratory distress syndrome (ARDS).  A long term goal of our research is to identify control points which augment barrier function as a means to improve the outcome of patients with ARDS and other forms of lung injury, particularly in the context of alcoholic lung syndrome and HIV-associated lung diseases.  More recently, we have begun to examine the impact of Cystic Fibrosis (CF) on airway barrier function with particular emphasis on how the airway barrier and epithelial cell repair is impaired in CF-related diabetes.

With my unique expertise, my focus at Emory University was to build a three-pronged approach for excellence in (1) Translational Research, (2) Clinical Service, and (3) commercialization of University technologies through small business opportunities.
 
In research, I have the expertise, leadership, and training in the biology of human blood antibody secreting cells (ASC) and BM plasma cells. As a translational scientist, I have focused my laboratory to study the human long-lived plasma cells (LLPC) in the bone marrow with the goal to understand novel intrinsic and extrinsic mechanisms of their survival. Our work identified the human LLPC phenotype using multi-color flow cytometry, morphology, and viral-specific Elispots from measles and mumps specific plasma cell responses in only one unique CD19-CD38hiCD138+ BM subset.  Using a combination of next generation sequencing to follow VH clones in the plasma cell subsets combined with state-of-the art proteomics, we directly linked the of serum viral-antibodies to the one unique cellular compartment (LLPC) in the human BM.  This work identifies the human LLPC compartment for the first time and provides the basis to identify novel mechanisms of plasma cell survival for the persistence of protective antibody secretion.
 
Within the past 3 years, I have also built the Adult Asthma Allergy and Immunology Program at Emory University with new clinical service line to provide state-of-the-art care for patients with severe asthma and complex allergic and immunological diseases.  This program works closely with established expertise at Emory in Pediatric Immunodeficiency, Otolaryngology in the Rhinology and Voice Clinics, Interventional Pulmonary, and Dermatology. The goals of this program are to provide novel immune therapies through clinical trials and compassionate use.  In addition to providing excellence in clinical care, I have developed a translational research program to understand the basic immune cellular mechanisms of IgE mediated allergic diseases with support from both NIH and Pharmaceutical research grants.
 
Lastly, I have been working at the interface of academic and small business enterprises to further commercialize university-based technologies with support from the Emory Technology Transfer Office, Georgia Research Alliance (GRA) programs, Center for Disease Control (CDC) and Small Business Innovative Research grants. We have been developing novel immune-based diagnostic methods for infectious diseases and new pharmaceutical research reagents to enhance antibody secretion and survival of plasma cells for the biologics industry.

Assistant Professor of Medicine
Director, Atlanta VA Medical Center Medical Intensive Care Unit

I have been at Emory since 2003, when I started my intern year.  I completed residency and fellowship in the Emory program and joined the faculty of the VA section in 2009 with a funded 2-year career development grant.  I completed the Masters of Science in clinical research (MSCR) program in 2013 and received a 5-year career development award grant from the VA.  My research involves clinical translational projects evaluating the role of alcohol abuse in predisposing individuals to pneumonia and acute lung injury.  Specifically, I investigate the role of zinc deficiency and oxidative stress on alveolar macrophage immune function and am in the middle of a large 5 year randomized clinical trial evaluating the role of dietary antioxidants and zinc on lung immune function. 

I have not previously worked with fellows, but would be available as a secondary mentor and for collaboration on projects that involve the role of alcoholism in lung disease.  I have co-mentored medical students who work in the laboratory setting and I have a strong interest in clinical research.  I am the medical director of the MICU at the VA and have a strong clinical interest in critical care ultrasound.  I have experience with writing IRB protocols and would be available as a resource or mentor for any fellows who may have an idea for a research project.

After completing my training in Infectious Diseases and Critical Care Medicine, I came to Emory as a clinical educator in 2014. My current clinical focus involves nosocomial infections, infection control and antibiotic stewardship in the ICU. During my fellowship, I focused on strengthening antibiotic stewardship efforts through penicillin skin testing and taught hundreds of medical students, residents, pharmacists, fellows, faculty, and nurses how to properly perform and interpret the procedure. This instrument became widely used at Vidant Medical Center to improve antibiotic stewardship efforts and dramatically reduce healthcare costs.

I also held teaching seminars for ICU providers on optimal antimicrobial therapies for certain diagnoses based on up-to-date guidelines and evidence based research. I wrote and edited a book, Bedside Critical Care Guide, in which I helped teach medical students, residents, and fellows how to write book chapters in scholarly texts. I was heavily involved in teaching medical students, residents, and fellows common procedures performed in the ICU. I also enjoy teaching trainees the basics of microbiology and antimicrobial pharmacology. My teaching in these areas have been recognized and I have gratefully been awarded for these projects. As I am still in the beginning of my career, I am actively involving myself in a variety of research projects, teaching opportunities, and institutional committees.

Trainees who wish to work with me should have an interest in proposing, creating, implementing and measuring the effectiveness of novel techniques in education.

Section chief, Pulmonary and Critical Care, Atlanta VAMC

I recently joined the Division of pulmonary and critical care medicine at the Emory University in July 2014 and currently serve as the section chief at the Atlanta VAMC. For most of my career as a faculty I have worked on research projects with graduate and medical students, residents and fellows.  I was the Associate Director for the Pulmonary Fellowship program at the University of Illinois in Chicago (2005-2012) and played an active role in clinical and research training of residents and fellows. Extramurally I have served as a member of transition and training (MITT) committee of the American Thoracic Society (2007-2015) and  was an executive member of the American Lung Association in Chicago (2006-2012) where I was responsible for organizing research seminars for students, residents and fellows.  My mentees have presented abstracts at National and International meetings and have successfully published case reports, reviews and original research articles.  

The overarching focus of my research is defining lung immune response and mechanisms of lung injury. I am currently funded by the Department of Veterans affairs.  In particular my laboratory is focused on understanding the host pathogen interactions in difficult to treat infections such as P.aeruginosa, Achromobacter and NTM. We study the role of lipid mediators (prostaglandins)/PPARγ signaling and  superimmunoglobulin receptor TREM-1 in macrophages in lung infections. By defining the immune response we aim to develop immunomodulatory strategies in patients with difficult to treat or resistant infections. My clinical interests include  infections in patients with non-CF bronchiectasis and select immunocompromised patients.   I have mentored several graduate students, residents, post- doctoral fellows and junior faculty through my career.

My clinical, administrative and research interests center around the treatment of patients with life threatening illness. In addition to my administrative roles at Emory, I serve as the associate editor for the journal Critical Care Medicine, the editor for the Society for Critical Care Medicine’s podcasts, section lead  for the mechanical ventilation and sedation for the Surviving Sepsis Campaigns,  associate chair for the United States Critical Illness and Injury Trials Group, and chair of the Internal Medicine section of the society for Critical Care Medicine  I have mentored more than 15 medical students, residents, fellows and junior faculty.

My primary research interests are in the treatment of patients with sepsis and the complications of sepsis including sepsis induced Acute Respiratory Distress Syndrome and septic shock. This includes both clinical trials, implementation science work (with David Murphy) , attempts to identify sepsis patients in the prehospital phase (with Carmen Polito) and attempts with limit the development of ARDS in sepsis patients.  I have also recently led, with Greg Martin as co-PI , a multicenter study looking at the association of ICU structure and organization with in patient mortality. This work has led to some interest in examining factors that might modify effects of novel agents in clinical trials, and we are currently exploring ancillary studies from this database. A third new interest (with Mike Lava) focuses around identifying more patient centered outcomes for critical care trial primary outcome measures.

Faculty Associate for International Programs, Laney Graduate School

I came to Pulmonary Division at Emory in 2005 as an Assistant Professor. Since arriving at the Pulmonary Division, I have been consistently funded by the NIH and other Research Foundations.  I am very active in the Molecular and Systems Pharmacology Program that is part of the Graduate Division of Biological and Biomedical Sciences and serve on the Executive Board.  In addition to my research, I oversee the International Programs of the Laney Graduate School and am active in international recruiting and developing international exchanges.

My area of research interest is in cardiovascular pathophysiology.  Vascular reactivity is a major determinant of physiological parameters such as blood pressure. Constriction of the vessel results in an increased blood pressure whereas, dilation of the vessel decreases blood pressure. Endothelial cells line the blood vessel and can regulate diameter of blood vessels by releasing agents that constrict or relax vascular smooth muscle cells. Research in my laboratory focuses on examining the interaction between endothelial cells and vascular smooth muscle cells and how certain pathophysiological conditions impair vascular function. The four areas that are most heavily studied are 1) the mechanisms of pulmonary vascular disease and accelerated atherosclerosis in HIV infection; 2) the role of PPARg and its subsequent effects on NADPH oxidases in regulating endothelial function in pulmonary hypertension 3)  the mechanisms underlying blood storage disease (in collaboration with Dr. John Roback, Pathology) and 4) the development  novel rho kinase inhibitors for the treatment of pulmonary hypertension (a collaboration with Anacor Pharmaceuticals).  Models include wild type and knockout or transgenic rodent models. Models may be challenged with a high fat diet to study diabetes or exposed to chronic hypoxia as a stimulus for the development of pulmonary hypertension. Approaches include everything from whole animal physiology to understand the effects of these models on blood pressure or pulmonary hypertension, to isolated tissue studies examining vascular contractility, to cellular preparations to examine biochemistry.

I joined the Emory University faculty in 2015. Prior to coming to Emory, I completed internship and residency in Internal Medicine and fellowship in Pulmonary and Critical Care Medicine at Vanderbilt University, finishing in 2014. For one year between fellowship and joining the Emory faculty, I worked with a well-known pulmonary vascular disease clinician and expert in clinical trials at Baylor College of Medicine in Houston, TX.

My clinical focus is caring for patients with various forms of pulmonary vascular disease including pulmonary arterial hypertension, a disease which bridges the fields of cardiology and pulmonology. My patient care activities are at The Emory Clinic and Emory University Hospital. As a fellow, my mentored research project involved the study of interactions of metabolism and pulmonary vascular disease development utilizing rodent and cell models with a focus on molecular biology. With these and other projects, I’ve had the chance to organize and present research at local and international meetings, and write case reports, reviews and book chapters for publication. Through these, I have cultivated an inquisitive spirit and continue to build my skills of asking and answering important questions. At present and going forward, I plan a more clinical and translational research focus. Specifically, I hope to use next generation sequencing and -omics technologies to shed light on the mechanisms underlying clinically recognized differences in how patients with pulmonary arterial hypertension respond to available therapy.
 
In addition to caring for patients with pulmonary hypertension and striving to advance understanding of pulmonary vascular disease, I greatly enjoy working with learners of all levels – and this allows me to be an active ongoing learner myself! As a junior faculty member, I am fortunate to be involved in both clinical and didactic teaching. In addition to my clinical service, I give part of the pulmonary module for medical students.
 
My pursuit of utilizing -omics technologies for pulmonary vascular disease development is in its early stages. For currently interested students, residents and fellows, I have several clinical research pursuits that involve utilizing existing data or electronic records systems to define how pulmonary hypertension is recognized and treated at Emory and the Atlanta VA. Beyond my existing ideas, I am always willing to help develop a trainee’s research interests, especially those exploring a topic related to pulmonary vascular disease.

My research interests span the intersection between tobacco/nicotine use and lung physiology and disease.  I studied lung development using animal and cell culture models prior to arriving at Emory, particularly the importance of retinoic acid signaling in the differentiation and maturation of lung cells.  Upon arriving at Emory, I began studying how prenatal nicotine exposure affects lung development since maternal smoking is a significant risk factor for the development of asthma.  My publications demonstrate that prenatal nicotine exposure increases branching morphogenesis, the developmental program responsible for forming the conducting airways in the fetal lung.  This disruption in normal development leads to an increased number of small airways, increased airway remodeling and increased airway hyperresponsiveness.  These findings may partly explain why offspring of maternal smokers are more likely to develop asthma.   In 2009, I moved my research program to the VA and began studying how chronic nicotine exposure increases airway hyperresponsiveness using animal and human cell culture models from asthmatic patients.  Currently, my research focuses on the mechanisms through which chronic nicotine exposure stimulates nerve growth factor, a neurotrophin, to promote airway hyperresponsiveness and whether asthmatics have an accentuated response to nicotine exposure.  I have also been involved in clinical studies.  I was a site principal investigator for the Examinations of HIV Associated Lung Emphysema study led by Kristina Crothers at University of Washington.  Although the study is no longer enrolling patients, the study is still open for data analysis.  I am also a co-principal investigator for industry sponsored studies at the VA.  The most recent study is whether benralizumab, a monoclonal antibody directed against the IL-5 receptor, will reduce exacerbations in patients with moderate to severe COPD.  

I also serve as the Associate Program Director for the Pulmonary/Critical Care Medicine fellowship.  As such, I am very interested in fostering trainee scholarship.  I currently am the Medical Director of the Pulmonary Function Laboratory and have a clinical interest in lung physiology and cardiopulmonary physiology with exercise and would be very willing to discuss clinical projects related to either of these.  Outside of Emory, I am also involved in the American Federation for Medical Research as the Southern Section Chair this year planning the 2016 Southern Regional Meeting in New Orleans.  I have also been involved in the American Thoracic Society as a Planning Committee Member and a Program Committee Member for RCMB.

Assistant Professor of Medicine

I joined Emory University’s Alcohol and Lung Biology Center as a postdoctoral fellow in 2009.  I investigated the role of NADPH oxidases and TGFβ in ethanol-induced oxidative stress and alveolar macrophage dysfunction, leading to alcoholics’ increased susceptibility to respiratory infections.  In 2011, I received an F32 from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) to study the effect of peroxisome proliferator activated receptor (PPAR)g ligands on alcohol-induced alveolar macrophage dysfunction.  In January of 2013, Dr. Yeligar joined the faculty as an Associate in Medicine, where my F32 served as a natural extension to an American Heart Association National Scientist Development Grant in 2012 to study the effect of PPARg ligands on alcohol-induced alveolar macrophage oxidative stress by modulating microRNA expression. 

In September of 2013, I obtained a K99/R00 Pathway to Independence Award from the NIAAA to continue my studies on the role of microRNAs in modulating alcohol-induced alveolar macrophage oxidative stress and dysfunction.  The novel treatment strategies I have studied to mitigate the detrimental effects of chronic alcohol ingestion on alveolar macrophage function have included S-adenosylmethionine, the critical antioxidant glutathione, and PPARg ligands rosiglitazone and pioglitazone.  In 2015, I was promoted to Assistant Professor of Medicine.  My benchwork research focuses have developed into translational projects and ongoing collaborations with Dr. Ashish Mehta and Dr. Sushma Cribbs.   My aim is to translate my studies into human therapeutic strategies in improving lung immunity in subjects with a history of alcohol use disorders (Dr. Mehta) and subjects with HIV positive status (Dr. Cribbs).  My main research focus is to elucidate the molecular mechanisms contributing to alveolar macrophage oxidative stress and phagocytic dysfunction in various pathologies and to examine novel therapeutic strategies that can be translated into clinical studies to improve lung immunity.
