Thank you for visiting Yi Liu’s research webpage. You found me!

I am a Ph.D. candidate in the Department of Statistics at North Carolina State University. My research interests include causal inference for both observational and randomized studies, the analysis of novel and composite endpoints, data fusion, and federated learning for multi-source biomedical data. I am also broadly interested in applications to cardiovascular diseases, HIV/AIDS, congenital heart defects, and racial disparities in healthcare.
