Dr. Tsui’s overarching goal is to improve care delivery and health outcomes for persons who use drugs. 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. She is also is actively involved in leading training programs to create the next generation of Addiction Medicine-trained physicians who are committed to expanding evidence-based care for persons with substance use disorders.

Dr. Tsui mentors medical students, residents, fellows, and graduate students who are interested in health services and clinical research on substance use disorders, HIV prevention,  HCV elimination, and the integration of addiction services and primary care. She publishes in and is a regular reviewer/editor/commentator for peer-reviewed journals.
