Dr. Cohen's work focuses on several themes -- food security and economics for immigrants settling in the US (particularly immigrants from rural Mexico), the production, use and consumption of grasshoppers by Oaxacans and the presence and use of grasshoppers by immigrants to the US. Patterns of food use and access to food by people living in poverty and the relationship of poverty and food deserts to issues like obesity. He would very much like to tie the later to work with the mid-Ohio food bank.
Dr. Cohen's research focuses on three areas: migration, development and nutrition. Since the early 1990s he as studied the impact, structure and outcome of migration from indigenous communities in Oaxaca, Mexico to the US with support from the National Science Foundation. He has also conducted comparative research on Mexican, Dominican and Turkish migration. His work on traditional foods, nutrition and migration was supported by the National Geographic Society. In addition to ongoing work in Oaxaca, he is currently studying the migration of Mexicans to Columbus.
