Yezhen (David) Li, Ph.D.

​

I am a medical sociologist with a Ph.D. in Sociology and an M.A. in Statistics and Data Science from the University of Pennsylvania. ​​​Recently, I completed postdoctoral training at the Center of Economic and Social Research, University of Southern California.

 

My research centers on aging, health, social networks, and migration. Specifically, my ongoing projects focus on the following areas:

​

• Longitudinal dynamics of informal care receipts and implications for older adults' health outcomes

• Psychometric methods for measurements of later-life cognitive abilities

• Social relationships and the health of marginalized populations, including immigrants and racialized minorities

 ​​​

I have published first-authored articles in the Journal of Gerontology: Social Sciences and Society and Mental Health. My work has been recognized with the 2025 Douglas Holmes Emerging Scholar Paper Award from the Gerontological Society of America.

 

Alongside my research, I have taught undergraduate courses in introductory sociology, social statistics, medical sociology, and the sociology of mental health.
