Carole and Lawrence Sirovich Professor of Public Health, Professor of Biostatistics


My research concerns the development of statistical methods for missing data, causal inference, and sensitivity analysis, with focus on applications in HIV and behavioral sciences. I have a long-standing interest in HIV and AIDS, which still exerts an enormous burden on society, particularly the most vulnerable.  

As part of my collaborations in HIV, I serve as Co-Director of the Biostatistics Program for AMPATH, an international consortium of universities in the US, Canada and Kenya focused on treatment and prevention of HIV in Kenya; co-Director of the Biostatistics Core for the Lifespan/Tufts/Brown Center for AIDS Research; and PI for the Biostatistics Core for the Brown Alcohol Research Center for HIV. My basic and collaborative research is funded by the NIH and USAID.

I teach both introductory and advanced courses in biostatistics, and supervise 1-2 PhD students at any given time. Between 2003 and 2012 I directed the Biostatistics Graduate Program.

In addition to teaching and research, a significant recent focus involves biostatistics research capacity building at Moi University in Kenya.
