Heather J. Ribaudo

Principal Research Scientist




Heather Ribaudo (formerly Heather Beacon) is a Research Scientist at the Center for Biostatistics in AIDS Research (CBAR) and the Department of Biostatistics at Harvard University where she focuses on HIV and AIDS clinical trials research within the AIDS clinical Trials Group (ACTG). Dr. Ribaudo is also the Associate Director of the Biostatistics and Computational Biology core of the Harvard University CFAR.

Dr. Ribaudo received her Ph.D. from the Medical Statistics department of the London School of Hygiene and Tropical Medicine in 1996. Since joining CBAR as a post-doctoral fellow in 1997, Dr. Ribaudo has been involved in collaborative research in the HIV field and has been responsible for the design, monitoring, and analysis of many specific major NIAID-sponsored HIV clinical trials. Her research interests include the design and analysis of clinical trials in AIDS research particularly the choice, evaluation, and monitoring of surrogate endpoints, HIV-1 resistance, viral dynamics, and human genomics. She is also interested in the application of causal inference analysis for the estimation of treatment effects from observation data in HIV.
