Dr. Traci GreenDr. Traci Green, PhD, MSc, is an epidemiologist whose research focuses on drug use, opioid use disorder, and drug-related injury. She earned a Master of Science in Epidemiology and Biostatistics from McGill University and a PhD in Epidemiology from Yale University. She is Professor and Director of the Opioid Policy Research Collaborative at Brandeis University where she oversees research on the drug supply, overdose prevention, and risk mitigation following law enforcement and policy actions. She also co-directs the Center of Biomedical Research Excellence (COBRE) on Opioids and Overdose at Brown University Health’s Rhode Island Hospital, and is an Adjunct Professor of Emergency Medicine and Epidemiology at the Warren Alpert School of Medicine at Brown University and the Brown School of Public Health.

Dr. Green created the web app platform www.streetcheck.org to support the growth and excellence of community drug checking. She helped co-found www.prescribetoprevent.org for prescribers and pharmacists and its companion site www.prevent-protect.org for families, patients, and community organizations to improve naloxone access.

Christa Thomas-SowersChrista Thomas-Sowers (she/her) joined Dr. Green’s team at Brandeis University as the Community Engagement and Harm Reduction Program Manager in June of 2025. Christa’s background is in direct service, community outreach, and harm reduction work. From 2018-2025, she worked with the community in Woonsocket, Rhode Island to establish a street outreach program and open a thriving drop-in center focused on the needs of individuals who used drugs or were experiencing homelessness. Through these experiences, Christa developed a deep understanding of the gaps in care, and the need for more common-sense, evidence-based, and human-centered approaches to the ever-growing crisis of inadequate social support and an increasingly toxic drug supply. She plans to use this knowledge to bolster and continue the impactful research being done by the team at the Opioid Policy Research Collaborative.
