She earned her MS and PhD in Environmental Health through the Tufts School of Engineering in the Department of Civil and Environmental Engineering. She completed a post-doctoral fellowship in Cardiovascular Epidemiology at the Boston University School of Medicine. Her research focuses on developing and applying new methods to assess the health effects of environmental mixtures in observational studies. Through her exposure assessment and environmental epidemiology research, Dr. Corlin seeks to mitigate environmental health disparities.

Karen Freund

Karen Freund, MD, MPH

Karen M. Freund, MD, MPH is Physician-in-Chief for the Department of Medicine and the Sheldon M. Wolff Professor of Medicine at Tufts University School of Medicine. She is Associate Director for Research Collaborations within the Tufts Clinical and Translation Science Institute (CTSI), and teaches in the Sackler School of Graduate Biomedical Sciences.

Dr. Freund received her undergraduate degree from Harvard University, her MD from Stanford University School of Medicine and her MPH for Boston University School of Public Health. She is double boarded in Internal Medicine (residency at Cambridge Health Alliance) and Preventive Medicine (residency at Boston Medical Center) and completed a general medicine fellowship at Boston University.

Dr. Freund joined the Institute for Clinical Research and Health Policy Studies at Tufts Medical Center in 2012. Prior to this, she was Professor of Medicine and Epidemiology at Boston University School of Medicine and Public Health, Director of the Women’s Health Interdisciplinary Research Center, and Chief of the Women’s Health Unit at Boston Medical Center. She served as PI of the Boston University BIRCWH (Building Interdisciplinary Research Careers in Women’s Health) to mentor the next generation of clinical investigators in women’s health research.

Dr. Freund’s research has focused on addressing the social determinants of health which influence the receipt of health care services, which in turn lead to disparities in mortality. She has addressed a broad number of issues in the screening, diagnosis and treatment phases of health care. This has included looking at the role of patient beliefs and behaviors, physician attitudes and decision making, and the role of systems barriers, especially navigating the increasing complex health care system. Breast cancer has been a major focus, but the research has also addressed cervical and colon cancer, cardiovascular disease, diabetes, exercise, depression, eating disorders and domestic violence.

Thomas Stopka

Thomas Stopka, PhD, MHS

Dr. Stopka is an Associate Professor at the Department of Public Health and Community Medicine and the Clinical and Translational Science Institute at the Tufts University School of Medicine. His major research interests are opioid overdose and infectious disease epidemiology and prevention, geographic information systems (GIS), spatial epidemiology, health disparities, and global health. Through his research, Dr. Stopka explores the interconnectedness of substance use and misuse, social and behavioral risk factors, and overdose and infectious disease outcomes among high-risk and often hidden populations through community-engaged, interdisciplinary, multi-methods, applied epidemiological research studies.

Dr. Stopka has contributed to and led many multisite studies in which he has employed qualitative, quantitative, spatial epidemiological, and statistical modeling approaches to better understand and curb the overlapping opioid overdose, HIV, and hepatitis C virus (HCV) epidemics. He is currently MPI on a NIDA, SAMHSA, and CDC-funded clinical trial (4UG3-UH3 DA044830-03) to assess the effectiveness of a mobile HCV telemedicine-based treatment intervention among rural opioid users in New England. He is a Co-I on the NIDA-funded HEALing Communities trial (UM1DA04912) to reduce opioid overdose deaths by 40% in Massachusetts, and the site PI for the NIH and SAMHSA-funded Massachusetts Justice Community Opioid Innovation Network study (UG1DA050067), evaluating administration of medication for opioid use disorder (OUD) in seven houses of correction. Finally, Dr. Stopka is the PI of a CDC-funded (1NU1ROT000018-01-00) opioid vulnerability study in 11 states, in which his team is modeling regional vulnerabilities related to opioid overdose, HIV, and HCV.
