Yan Li

Professor, Epidemiology and Biostatistics

Dr. Yan Li is interested in combining her background in computer sciences, genetic and survey methodology with her research experience with National Cancer Institute to develop statistical methods for efficiently designing and analyzing complex samples in a biomedical setting. Particularly, her interests include improving population representativeness of nonprobability samples, health disparity analyses, genetic association using case-control, cohort and cross-sectional studies and surveys with complex designs.
