I am an associate professor of economics at Dartmouth College. My research examines why poor countries have remained poor for so long, and what policy interventions can help improve people's lives in developing countries. My team builds new open source economic data from information age sources like satellites, and private and government sector data exhaust.

Some of my recent projects have focused on judicial bias in India, the impacts of India's large-scale rural roads program, the impacts of mineral sector development, and on measuring intergenerational mobility in developing countries. I also have several projects on machine learning and statistical methods with applications to the U.S. mortality crisis.

I am founder of Development Data Lab and a creator of The SHRUG, which Sam Asher, Toby Lunt and I are turning into the best open data platform for socioeconomic research in India and beyond. My Google Scholar page is here.
