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 details of research funding, my school page, or fun experiments like music playlists.  Background is described in my AAEA Fellow’s bio and, more colorfully, in my ANH career journey.

I also maintain a separate page for my project on Food Prices for Nutrition, developing price indexes to track the most affordable ways to meet dietary needs. Through that project we help national governments and development agencies measure change in agricultural supply and the food environment, guiding intervention to improve each population’s access to healthy, sustainable diets. In August 2023, I summarized our global results for a U.S. audience at the National Academies that you watch in this 20-min video.

For news and event announcements I now use LinkedIn and am experimenting with Bluesky, but have not deleted old things on Twitter and Mastodon. Instructors, students and others could also look out for my forthcoming textbook with Amelia Finaret based on the course described at my teaching blog on Food Economics: Agriculture, Nutrition and Health.

Handbook chapter — if you read only one thing from me, make it this:
