I am a practicing general internist and investigator in the Division of General Internal Medicine at the University of California San Francisco. My overall research program aims to reduce health disparities and promote health equity among multiethnic and linguistically diverse adults by developing and evaluating innovative, patient-centered interventions.

I serve as the Co-Director of the UCSF Multiethnic Health Equity Research Center and Co-Director of the Asian American Research Center on Health. I serve as the UCSF Lead of the University of California Consortium on Asian American and Pacific Islander Policy & Community Priorities. In 2024, I was appointed to serve a four year term as a member of the Advisory Committee on Minority Health of the U.S. Department of Health and Human Services Office of Minority Health. I am also a member of the editorial board of the journal Health Equity after serving as an Associate Editor. I engage in clinical outpatient teaching of residents and research mentoring of trainees including predoctoral students. I also direct the UCSF Primary Care Residency Resident Scholarship Program.

My current partner-engaged and clinical practice-based research focuses on:
a) the impact of social determinants of health including race and ethnicity, language and culture on chronic disease care, particularly among those with multiple chronic conditions;
b) patient-clinician communication about social determinants of health and unmet health-related social needs such as food insecurity and transportation barriers;
c) use of photos as a tool to communicate about health and social factors important in chronic disease care. This work is based on the premise that photos can promote efficient information exchange and activate patients to communicate their complex lived experiences, including their goals and preferences that may otherwise be difficult to elicit or challenging to discuss in current clinical practice.
