Welcome to the Harvard Center for International Development’s Beyond COVID podcast. This podcast is a series of conversations with CID faculty experts on various key dimensions of COVID response and recovery. Our goal with these conversations, and with CID’s Beyond COVID research initiative, is to make use of lessons learned and capitalize on emergent innovations sparked by the pandemic in order to address losses and reimagine global development in the post-COVID era. On March 3, 2022, we were joined by Walter Willett, Professor of Epidemiology and Nutrition at Harvard T.H. Chan School of Public Health and Professor of Medicine at Harvard Medical School. CID Student Ambassador Kerianne DiBattista sat down with Walter to discuss nutrition, climate change, and COVID-19.
