Dr. Judith Tsui is a Professor of Medicine at the University of Washington, based at Harborview Medical Center and Evergreen Treatment Services. As a clinician investigator, her overall goal is to improve care delivery and health outcomes for persons who use drugs who are at risk for HIV and HCV. Dr. Tsui’s current research is focused on innovative health service delivery interventions to expand access, and improve adherence, to potentially life-saving medications for persons who use drugs, including medications for opioid use disorder, HCV, and PrEP. Additionally, she has conducted research on substance use, pain, and opioid prescribing for persons living with HIV.

Dr. Tsui mentors medical students, residents, fellows, and graduate students who are interested in clinical research on substance use disorders and related co-morbidities such as HCV. She publishes in peer-reviewed journals and contributes to the popular press. 

Dr. Tsui welcomes emailed queries about research opportunities.
