Byron AuYeung

Byron AuYeung

What is your professional background?
I am an Assistant Professor in the Division of Rheumatology and the Lowance Center for Human Immunology. I received a PhD in Immunology from the University of Rochester and completed my postdoctoral training in the lab of Dr. Arthur Weiss at the University of California, San Francisco.

In what division do you work, and who is your mentor?
I work in the Division of Rheumatology, and my mentor is Dr. Inaki Sanz (Rheumatology/Immunology).

Briefly describe your research. Why it is important?
I am a cellular immunologist by training, and my interests include the complicated signals that activate T cells. We know most of the proteins involved in the process but know less about when or how much signaling is required for certain types of T cell immune responses. I have been working on methods to modulate T cell receptor signals and read out signal accumulation for T cells – processes similar to the brakes and odometer on a car. Ultimately, we want to better understand the signaling requirements for T cells, so we can design more targeted therapies for T cell response-driven autoimmune diseases.

What do you like most about Emory?
I like being surrounded by the many smart people here!

What is your favorite movie or TV show?
I love the Simpsons.

What do you like to do in your spare time?
I grew up in Canada, so I enjoy watching or playing hockey when I can.


Raymond Lynch
Raymond Lynch (Renal Medicine)
~ 4th annual Health Services Research Day 3rd place poster presentation winner
What is your professional background?
I am a liver transplant surgeon. I chose transplant because of the many unanswered questions regarding how patients become ill, are diagnosed, are screened and selected, and are managed after transplant. Health services research has the potential to shape patient care immediately and directly, and allows me to channel clinical dilemmas and frustrations into a productive means of assessing and improving outcomes.
In what division do you work, and who is your mentor?
I work in the Division of Transplant Surgery. My mentor is Dr. Rachel Patzer (Transplant Surgery/Renal Medicine). Briefly describe your research.
Why it is important?
We are studying how patient level factors, other than the biological severity of their disease and the regional supply of organ donors, shape the mortality risk of end stage liver disease patients on the waitlist. These data are important because access to transplant has become synonymous with organ availability. Our findings suggest that both locally – at the level of the transplant center – and nationally, we should consider vulnerable populations for enhanced priority in organ access to minimize preventable deaths.
What do you like most about Emory?
We have a broad range of clinical and academic experience, and an institutional culture that supports asking questions and working together. We used to have a Dunkin Donuts, and we may again.
What is your favorite movie or TV show?
Silicon Valley is my favorite TV show.
What do you like to do in your spare time?
I don’t have much spare time.

Taylor MelansonTaylor Melanson

2nd place poster presentation, 4th annual Health Services Research Day

What is your professional background?
I am a 4th-year PhD student in health services research and health policy with a concentration in health economics (Laney Graduate School). Before coming to Emory, I received a BA in economics and German from Washington & Lee University.

In which division do you work, and who is your mentor?
Since August of 2015, I have been working in the Emory Division of Transplantation with Dr. Rachel Patzer (Surgery/Renal Medicine).

Briefly describe your research. Why it is important?
My research focuses on access to care for end-stage renal disease (ESRD) patients. ESRD affects almost 700,000 Americans, and, unfortunately, disparities can be seen at most, if not all, stages of care provision for these patients. I am particularly interested in the effect that policy can have in addressing disparities and improving access for disadvantaged patients. This work is important because so many people suffer from this disease and sub-optimal care decreases their quality of life and simultaneously creates a large financial burden on our health care system.

What do you like most about Emory?
Emory is an incredibly welcoming place, and I have found no shortage of talented and collaborative individuals who are interested in mentoring junior researchers. As someone who grew up outside of Boston, I am also a big fan of the weather here.

What is your favorite movie or TV show? 
Game of Thrones is definitely my favorite TV show, and it's based on my favorite book series.

What do you like to do in your spare time?
I try to take advantage of Atlanta's great weather and run or hike whenever I have the chance. I am also really into baking bread.


Wen LiuWen Liu
4th Annual Health Services Research Day 1st place poster presentation winner 
What is your professional background?
I am currently pursuing an MD/MPH (Epidemiology) and will be applying to Urology residency programs this fall. Before starting medical school, I worked as a Global Academic Fellow in Biology at NYU Abu Dhabi. I received my BA in Neuroscience and Behavior from Columbia University.
In what division do you work, and who is your mentor?
My mentor is Dr. Christopher Filson in the Department of Urology.
Briefly describe your research. Why it is important?
My research interests lie within health services in urologic oncology, specifically with respect to use of MRI-guided biopsies in prostate cancer diagnosis, treatment and outcomes, as well as the effect of state-level Medicaid expansion on access to and disparities in prostate cancer care. Prostate cancer is the only solid organ tumor not traditionally diagnosed with targeted biopsy, and recent reports have found increased cancer detection using MRI-guided prostate biopsies compared to transrectal ultrasound-guided biopsies. Understanding utilization patterns of this newly developed MRI approach is important for identifying potentially disparate care and effects on cancer outcomes and health policy/economics. Additionally, assessing health policy decisions on access to cancer care is critical, especially in more vulnerable populations that may be disproportionately affected.
What do you like most about Emory?
I am impressed by the accessibility of the faculty and the level of mentorship I have received, which has greatly impacted my personal and professional development.
What is your favorite movie or TV show?
I am eagerly awaiting the return of Game of Thrones and Stranger Things!
What do you like to do in your spare time?
I love traveling, running, playing with my dog (Teddy), cooking, and hanging out with friends.

Ceclie Lahiri

Cecile Lahiri, MD, MSc (Infectious Diseases) 

What is your professional background? 

I am an assistant professor in the Division of Infectious Diseases, working with Dr. Igho Ofotokun. I received my MD from the University of North Carolina and completed my internal medicine and infectious diseases fellowship training at Emory. In 2013, I received a master of science in clinical research at Emory.

Briefly describe your research. Why it is important?
Despite combination antiretroviral therapy, HIV has not been eradicated, and emerging evidence suggests that multiple sites in the body act as reservoirs and play critical roles in viral persistence. My research focuses on evaluating barriers to HIV reservoir eradication, including pharmacologic barriers as well as host factors that may impact our ability to eliminate the virus. I am particularly interested in evaluating sex differences within these reservoir sites and how sex impacts the size and viral dynamics of reservoirs over time. Sex differences may influence reservoir characteristics and the host response to therapeutic interventions. Despite this, women continue to be largely underrepresented in HIV clinical cure studies despite accounting for more than 50% of HIV-infected persons worldwide. I plan to help fill this knowledge gap by prioritizing the enrollment of women in clinical studies so that curative interventions can have maximal impact on both sexes.

What do you like most about Emory?
Emory’s collegial environment and the enthusiastic approach to multidisciplinary collaboration is impressive.

What is your favorite movie or TV show?
I am fascinated by any show that involves spies, so “Homeland” and “The Americans” are two of my favorites!

What do you like to do in your spare time?

JWJinhu Wang, Ph.D. (Cardiology)

Dr. Wang is an assistant professor in the Division of Cardiology. He received his PhD in Developmental Biology at the Chinese Academy of Science and completed his postdoctoral research training with Dr. Kenneth Poss at Duke University. His broad research goal is to understand how regenerative responses to injury have been optimized in non-mammalian vertebrates like zebrafish in order to identify potential targets that are responsible for regenerative deficiencies in mammals. The coronary vasculature supplies oxygen and nutrients to a large region of myocardium, and re-vascularization is considered an important step for heart recovery. Adult zebrafish have a dense coronary vasculature, and regenerated myofibers become re-vascularized in a few weeks. Using this model, Dr. Wang investigates the molecular mechanisms of coronary re-vascularization during heart regeneration by utilizing genetic manipulation and live imaging techniques. His results will provide insights into the cardiac repair process in mammals. In his free time, he enjoys traveling, hiking, tennis, fishing and swimming.


KTKiyoko Takemiya, MD, PhD (Cardiology)

Dr. Takemiya joined Emory from Kurume University in Japan. She recently received an American Heart Association Scientist Development grant to support her research on the detection of bacterial infections associated with medical devices. Currently, the diagnosis of device infection is made based on symptoms or clinical signs, and when it is diagnosed, the infection has already expanded and damaged the surrounding tissue. Dr. Takemiya’s work aims to detect infection in the very early stages with no clinical signs or symptoms, which will help to improve the prognosis of patients and to reduce unnecessary surgeries.

To detect small amount of bacteria, Dr. Takemiya’s team focused on the differences in sugar metabolism between bacteria and mammalian cells. Maltodextrin, a kind of sugar, is used by bacteria as a major energy source through the “maltodextrin transporter,” but cannot be internalized by mammalian cells. The maltodextrin transporter is large enough to pass an imaging probe conjugated with maltodextrin or its analogue, leading to accumulation in bacteria, and allowing sensitive and specific detection of bacteria. Dr. Takemiya uses rat models to test these maltodextrin and maltodextrin analogue-based imaging probes for near infrared imaging and positron emission tomography (PET) imaging to detect the existence of bacteria. In her free time, Dr. Takemiya enjoys cooking, reading, playing with jigsaw puzzles, and crafting.

BWBrandi Wynne, PhD (Renal Medicine)

Dr. Brandi M. Wynne is an instructor of medicine in the Division of Renal Medicine with a background in cardio-renal physiology and pharmacology. Previously, Dr. Wynne was a postdoctoral fellow under Dr. Robert Hoover, where she focused on the hormonal regulation of the sodium chloride cotransporter (NCC) and the epithelial sodium channel. Her current research investigates the role of inflammation in the etiology of salt-sensitive hypertension. Hypertensive patients frequently have a normal level of aldosterone, the main ligand for the mineralocorticoid receptor (MR), which regulates sodium transport proteins in the distal nephron. However, these patients often have indices of aldosterone excess and respond positively to MR antagonists, suggesting that there are alternative mechanisms of MR activation. Dr. Wynne’s research has shown that interleukin-6 (IL-6) plays a role in this process. She recently discovered that IL-6 transactivates the MR, leading to activation of the NCC. Understanding how renal-specific immune cells and cytokines regulate sodium homeostasis is the focus of her NIH NIDDK K01 application. In her spare time, Dr. Wynne enjoys the arts, politics, and traveling as much as possible.


SYSamantha M. Yeligar, MS, PhD (Pulmonary)
Dr. Samantha M. Yeligar is an assistant professor of medicine in the Division of Pulmonary, Allergy, Critical Care and Sleep Medicine. She was recently awarded a National Institute on Alcohol Abuse and Alcoholism R00 grant to study the “Effect of Peroxisome Proliferator Activated-Receptor Gamma (PPARγ) Ligands on Alcohol-Induced Alveolar Macrophage Oxidative Stress.” The project focuses on alcohol-mediated down-regulation of NADPH oxidase-related microRNAs that contribute to alveolar macrophage dysfunction, which can be reversed by treatment with PPARγ ligands. The considerable translational impact of these investigations on the management of alcoholic patients to mitigate their susceptibility to developing respiratory infections will set the stage for future clinical studies. In her free time, Samantha loves to paint with acrylics, draw with charcoal, travel, and concoct interesting culinary experiments for which her friends volunteer as study subjects (not to worry, everyone remains friends).

imageClintoria Williams, PhD (Renal Medicine)

Dr. Williams is a renal physiologist in the Division of Renal Medicine. Her research interest focuses on the pathophysiology of kidney disease. Her work has identified a key functional difference in the isoforms of calcineurin, a family of ubiquitous calcium-dependent phosphatases. These enzymes contribute to the regulation of sodium channels in the distal nephron of the kidney and subsequently blood pressure homeostasis. Notably, patients that take calcineurin inhibitors for immunosuppression frequently develop hypertension. Since current drugs that inhibit calcineurin do not discriminate between the isoforms of the enzyme, there is an opportunity to refine pharmacological interventions to selectively target calcineurin isoform(s) implicated in the immune system versus isoform(s) involved in sodium regulation by the kidney. Recently, Dr. Williams received American Heart Association funding on her project, entitled “Selective regulation of distal nephron sodium handling by calcineurin isoforms.” In her free time, she serves as a motivational speaker, life coach, personal chef, and chauffeur to her children.
Learn more about Dr. Williams’ work at the 9th annual Department of Medicine Research Day on Friday, 10/28 in the Cox Hall Ballroom, where she will present "NADPH oxidase-2 mediates zinc deficiency-induced oxidative stress and kidney damage."

Highlighted-Researcher

Madeleine Hackney, PhD (General Medicine and Geriatrics)

Dr. Hackney’s DREAMS (Developing a Research Participation Enhancement and Advocacy Training Program for Diverse Seniors) project grew out of an ongoing problem in clinical research. Older adults with low socioeconomic status and/or from racial or ethnic minority populations are historically underrepresented in research because of multiple barriers, including distrust of the research community, difficulties with access, ageism, health literacy challenges, and strict trial inclusion criteria. To help break down the existing barriers and build relationships with these underrepresented populations, Dr. Hackney decided to use the tango to treat mobility problems in people with Parkinson’s disease. While some of the participants danced, those assigned to the control group attended educational sessions on various health issues. The interactive educational sessions were so popular, both with learners and the teachers, that Dr. Hackney suspected they could serve to bring together a group of diverse seniors for the DREAMS project. Funding from the Patient Centered Outcomes Research Institute (PCORI) gave her the chance to empirically demonstrate her theory.
