About
Dr. Tammy Chang is a health services researcher and practicing family physician with a passion for adolescent health, specifically, breaking the cycle of poverty and poor health among adolescent mothers and their children via community-engaged research.

She actively mentors numerous high school students, undergraduate students, graduate students, medical students, and post-doctoral fellows to fill the pipeline of future health services researchers.
