Agriculture and the Environment: This is the constant theme of my work since my undergraduate days. Within the AFE program, this incudes assessments of resource use (land, water, etc.) by current and future production strategies and systems. My current efforts are informed by having conducted decades of field and laboratory research on crop management, alternative crop development, short- and long-term effects of cropping systems on potato yield and quality, management strategies to improve soil quality, manure nitrogen and phosphorus availability, soil carbon sequestration and cycling, emission of greenhouse gases from high-value production systems, and grain production for organic dairy systems. Sustainable and Equitable Food Systems: Environmental outcomes are one of several realms or domains that are encompassed by a Sustainable Food System. The Friedman School is uniquely placed to link agriculture, nutrition and health, economics, and individual and societal well-being. Of particular interest is the role of diets as a driver of sustainability outcomes, and includes policy-oriented efforts such as my role advising the 2015 Dietary Guidelines Advisory Committee, to include sustainability in the Dietary Guidelines for Americans. Interdisciplinary Education and Mentoring: The AFE program is inherently interdisciplinary, as is the Friedman School. My particular interest is to provide education and research opportunities so that students can develop the specific skills necessary to work at the interface of different disciplines or domains.

Thomas Stopka

Dr. Thomas Stopka, PhD, MHS, is an Epidemiologist and Professor with the Department of Public Health and Community Medicine at the Tufts University School of Medicine. Dr. Stopka's current mixed methods research focuses on the intersection of substance use disorder, opioid overdose, and infectious diseases (HCV, HIV, STIs). He employs geographic information systems (GIS), spatial epidemiological, qualitative, and biostatistical approaches in multi-site, interdisciplinary studies, and public health interventions to better understand and curb opioid-related morbidity and mortality. He is currently MPI on four clinical trials and observational studies funded by the NIH, CDC, and SAMHSA to test new mobile telemedicine-based HCV treatment and harm reduction models; employ Bayesian spatiotemporal models to predict opioid overdose spikes to inform pre-emptive public health responses; and evaluate the overdose prevention impacts of administration of extended-relief buprenorphine in corrections facilities, and examine xylazine exposure and the risk of skin and soft tissue infections among people who inject drugs. Dr. Stopka is also Co-Chair of the Tufts Research Cluster focused on Equity in Health, Wealth, and Civic Engagement, and Co-Chair of the Public Health and Community Medicine Departmental Research Committee at Tufts. He teaches courses in GIS and spatial epidemiology, research methods for public health, and epidemiology. He enjoys mentoring research assistants, graduate students, postdoctoral fellows, and faculty.
