My research uses economics to inform and improve the food system, especially in Africa.  I began at Purdue University with a focus on markets and trade, then innovation and information, and since moving to Tufts in 2010 have focused primarily on how to improve human nutrition.  A narrative record of USDA-funded research at Purdue from 1998 to 2010 is available through my annual reports in CRIS.
