Susan M Ray, MD
Professor of Medicine
Emory University School of Medicine
Susan M. Ray, MD is Professor of Medicine in the division of Infectious Diseases at Emory University School of Medicine. Dr. Ray’s academic and clinical pursuits are centered on the epidemiology, prevention, and treatment of infectious diseases affecting the urban, indigent, minority population served by Grady Health System; she is the Hospital Epidemiologist for Grady Health System. Dr. Ray has been a clinician at the Fulton county TB clinic since 1999 and in 2010 became the medical consultant to the GA Dept of Public Health TB program. Her specific areas of interest include: the management of co-infection with HIV and TB and defining the immune response to Mtb infection.
Dr. Ray is the founder and physician director of the Woodruff Health Sciences Center Needlestick Prevention Center. Dr. Ray has been an investigator with the GA Emerging Infections Program since 1998 and is the lead investigator for GA EIP Healthcare Associated Infections and Community Interface (HAIC). Dr. Ray is also the Medical Consultant for the GA DPH TB Program. Dr. Ray has served as a member of the Emory Institutional Review Board since 2003; in 2006 she was appointed Vice-Chair to the IRB.
Dr. Ray's research activities focus on the epidemiology, prevention and treatment of infectious diseases affecting the urban indigent minority population both in the community and in the hospital:
- Epidemiology and prevention of pneumococcal disease
- Racial and ethnic disparities in adult immunization rates
- Hospital and molecular epidemiology
- Clinical trials of therapy of tuberculosis infection and disease
- Molecular epidemiology of tuberculosis
- Molecular and clinical epidemiology of foodborne diseases
Local pneumococcal disease surveillance data is analyzed to assist in developing an institution-wide effort to increase the use of pneumococcal vaccine. Patient and provider interventions to address the underutilization of adult vaccines among African-American patients are designed and evaluated. Nosocomial bloodstream infections are of particular interest in the field of hospital epidemiology with a focus on using surveillance data to design interventions to prevent these infections. The epidemiology of blood culture contamination at Grady has been studied and cost-benefit analyses constructed to demonstrate the need for and benefit from a dedicated blood culture collection team. Clinical trials of tuberculosis therapies are designed and conducted through the CDC Tuberculosis Treatment Consortium. Molecular biology techniques are applied in the study of the epidemiology of tuberculosis transmission at an institutional, metropolitan, and international level. Analysis of multi-site U.S. surveillance data (Emerging Infections Program) for yersiniosis performed for presentation and publication. Bacterial isolates collected by active population-based surveillance for foodborne diseases are analyzed by pulsed-field gel electrophoresis.
