Research Interests

I conduct applied research on the design of domestic and international policies for agriculture and natural resources. My aim is to determine the effectiveness and efficiency of these policies and to generate policy recommendations. Recent projects have focused on analyzing domestic support policies for agriculture, the design of agri-environmental programs, climate change policies for agriculture, and the evaluation of rural development policies.

Outreach/Extension Interests

I do not have a formal extension appointment, but I am often asked to make presentations on policy issues affecting agriculture.
