Stuart C. Ray, MD, FACP, FIDSA serves as Vice Chair of Medicine for Data Integrity and Analytics and is a Professor in the Division of Infectious Diseases within the Department of Medicine, with secondary appointments in Viral Oncology and Health Sciences Informatics. He is Scientific Director of the JHU Laboratory for Integrated NanoDiagnostics, directs the virology laboratory and is a clinical investigator in the Center for Viral Hepatitis Research in the Division of Infectious Diseases. He is a faculty member of the Graduate Immunology program, the Graduate Pharmacology program, and of the Janeway Firm of the Osler Medical Service.
Dr. Ray received his M.D. from Vanderbilt University School of Medicine in 1990. After an internship and residency at Johns Hopkins Hospital, he continued there as an Assistant Chief of Service and fellow in Infectious Diseases. During his fellowship, he studied the immunology and sequence variation of HIV in the laboratory of Dr. Robert Bollinger. During that time, he developed an interest in HIV sequence variation during antiretroviral therapy in a productive collaboration with Dr. Robert Siliciano that continues to the present.
In 1997 Dr. Ray joined the Johns Hopkins faculty, and under the mentorship of Dr. David Thomas shifted his primary research focus to hepatitis C virus (HCV). His laboratory work has focused on the sequence variation of HCV during acute and chronic infection, developing and applying computational and molecular biology tools to underlying mechanisms including stochastic variation, immune selection, and viral fitness. He continues to care for patients with HIV, HCV, and other infectious diseases.

Research & Publications
Dr. Ray's research focuses on innovative nanodiagnostics, with a long term interest in hepatitis C virus (HCV) sequence evolution and persistence. HCV affects more than 3 million people in the United States and nearly 200 million worldwide. Current treatment is highly effective but expensive, and most infected people are unaware of their infection. Thus, Dr. Ray remains dedicated to enhanced screening, access to care, and rational vaccine development for HCV.
