Research and Interests

My research uses epidemiologic tools to identify and seek possible solutions for public health problems relating to health inequities. I have ongoing research projects in two main areas:

  1. Immigrant health. Immigrants undergo a transition in health after migrating to the US, creating disparities that are probably preventable. My research in this area aims to identify predictors of disease risk in Chinese immigrants, including lifestyle behaviors, psychosocial factors, and living in an ethnic enclave.
  2. Ultra-processed foods in the US diet. Ultra-processed foods dominate our food environment and are linked to poor diet quality and disease risk, but research in this area remains very controversial. Our objectives in this project are to improve and standardize measurement of ultra-processed foods, describe purchase and intake of these foods in the US, and quantify their associations with disease risk.
