Hello! 

I was born and raised in Zhengzhou, Henan Province, China. My Chinese name: 俞以川. 

I'm a Ph.D. student of epidemiology at the University of Southern California. I use population-level data from large cohort studies and electronic health records to study cancer etiological biomarkers. 

Where do I often spend my functional time?
