I am a physician and Assistant Professor of Medicine and Health Policy at the Perelman School of Medicine at the University of Pennsylvania and a Senior Fellow at the Leonard Davis Institute of Health Economics.

My research focuses on the life-course origins of health and socioeconomic inequality. I study:

1) The effects of early life interventions on adult health and well-being, and the mechanisms underlying these links.

2) The relationship between economic opportunities and health behaviors and outcomes.

3) The short- and long-run returns of public health and social sector programs.

4) Behavioral responses to, and demand for, HIV prevention and treatment programs.
