I have published empirical economics and health services research on the elderly, adolescents, HIV/AIDS and managed care. Most recently, I have been working on the labor market consequences of the obesity epidemic. I have researched the regulation of the viatical-settlements market (a secondary life-insurance market that often targets HIV patients) and summer/winter differences in nutritional outcomes for low-income American families. I am working on a project examining the labor-market conditions that help determine why some U.S. employers do not provide health insurance.
I am an infectious diseases physician and an Associate Professor of Medicine in the Division of General Internal Medicine and a Stanford Health Policy affiliate. My research interests involve understanding the relationship between policies and health outcomes in developing countries. I explore how decisions about foreign assistance for health are made, and how those decisions affect the health of those whom assistance aims to serve. I am also a disease modeler, and use that skill to explore issues of resource allocation in low and middle-income countries with cost-effectiveness analyses.
Assistant Professor of Neurology, Medicine (BMIR/QSU) and, by courtesy, Biomedical Data Science
I am interested in bridging new technologies such as genomics and machine learning with clinical medicine. I am also interested in the use of Twitter for scientific communication and medical education. Clinal focus: Dermatology.
