Gregory D. Zimet, PhD, HSPP

Professor of Pediatrics


Dr. Zimet is a Clinical Psychologist and Professor in the Department of Pediatrics. Since he arrived at IU School of Medicine in 1993 he has guided an extensive and multi-faceted research program focused on attitudes about, and acceptance of, vaccines for the prevention of sexually transmitted infections (STI), including human papillomavirus (HPV) vaccine. More recently, Dr. Zimet's research also has involved randomized clinical trials designed to evaluate the effects of brief health communication messages on hepatitis B virus (HBV) and HPV vaccine uptake and on acceptance of HIV testing. In addition, through his involvement over the past 5 years in the Adolescent Medicine Trials Network (ATN) for HIV/AIDS Interventions Dr. Zimet has expanded his research focus to examine factors related to recruitment of adolescents into biomedical HIV prevention clinical trials. Biomedical trials that may ultimately involve adolescent recruitment include pre-exposure prophylaxis (PrEP), HIV vaccine, and microbicides. Dr. Zimet's research has been funded by NIH, CDC, and private industry. He collaborates with researchers throughout the U.S. and from several other countries who represent many different disciplines including health marketing, medicine, psychology, biostatistics, nursing, and public health. Manuscripts published during the past year include 9 articles on HPV vaccination, 3 on microbicide acceptability among adolescents, and 2 on attitudes about HIV and herpes simplex virus type 2 (HSV 2) testing. Dr. Zimet has served as a research mentor to 5 physician fellows, over 20 pre- and post-doctoral fellows in psychology, social work, health behavior, and nursing, and several junior faculty in the Department of Pediatrics and the School of Nursing.
