Hi – thanks for visiting. I am a Professor at Tufts University, in the Friedman School of Nutrition with a secondary appointment in the Department of Economics. Timeline of links below summarize recent work, or click links for publications and funding, music playlists, my school page, AAEA bio and ANH career journey.
Blog posts, photos and outreach are on twitter and on my FoodEcon site, and I maintain a separate site for my project on Food Prices for Nutrition.
