Robert Gross, M.D., M.S.C.E.

Robert Gross is an Associate Professor in Medicine in the Division of ID and Associate Professor of Epidemiology in the Department of Biostatistics and Epidemiology as well as a Senior Scholar in the Center for Clinical Epidemiology and Biostatistics where he received formal training in clinical research culminating in a Masters of Science in Clinical Epidemiology. His research is focused on clinical and virological outcomes in the treatment of HIV infection. A particular interest is the problem of adherence to antiretroviral therapy including methods of measurement of adherence, changes in adherence over time, barriers to adherence in both developed and developing world settings, and trials of adherence interventions. Other interests include HIV pharmacoepidemiology more broadly, including observational studies and clinical trials of antiretroviral therapy, and HIV health services research. He serves as a clinical research mentor to fellows in the Masters of Clinical Epidemiology as well as to medical students and residents interested in pursuing HIV clinical research interests in Philadelphia and abroad (e.g., Botswana, Dominican Republic). Dr. Gross's outpatient clinical work is focused on the care of HIV patients and is based at the Philadelphia Veterans' Administration Medical Center. His inpatient work is divided between HIV and general ID at both the Philadelphia VA and the Hospital of the University of Pennsylvania.
