My specialties include Internal Medicine and Preventive Medicine. I have a focus on heath disparities including TB, Hepatitis B, cancer, Native American Health and Asian American Health.

In the past, I have worked on Hepatitis B health bulletins in New York City and original research publications on cancer disparities in the Asian American population in New York City. Previously in the last 2 years, I was the Hepatitis B Program Director at the Charles B. Wang Community Health Center in New York City.
