Justin’s research focuses on understanding long running, persistent patterns in economic growth and development. In doing so, he has examined historical, cultural differences that are observed in the genes of contemporary populations—a prime example being lactose tolerance. And his current work focuses on understanding the persistence of populations and economic output from the historical locations of past civilizations. Recent work also explores the aggregate impacts of redistributive policies, particularly in India. Justin received his B.S., M.S., and Ph.D. from Louisiana State University and was an assistant/associate professor at the University of California, Merced before joining Tulane University.
