My research focuses on care delivery for vulnerable and stigmatized populations, particularly integrating patient-centered approaches within population health management. I believe interventions such as medications for substance use disorders, harm reduction strategies, and mindfulness-based therapies empower individuals and increase their sense of agency, while enhancing their quality of life and health outcomes.
