Background

Ruizhe Chen, Ph.D. is currently a tenure-track faculty at the Division of Quantitative Sciences, under the oncology department of Johns Hopkins University School of Medicine. His main duties include conducting collaborative and methodology research as well as teaching an intro-level R data analysis course. His statistical methodology research mainly focuses on Bayesian statistics, restricted mean survival time, and multivariate count data generation and modeling. For collaborative research, he mainly works with Hopkins' breast cancer study team to develop translational imaging and blood biomarkers for clinical response predictions, as well as design and analyze clinical trials. He's also interested in interdisciplinary research between biostatistics and bioinformatics such as informative missing data pattern discovery and application of zero-inflated count data in high-dimensional settings.
