Biosketch
Dr. Chen is a biostatistician specializing in modeling complex structured biomedical data, including spatiotemporal dependence in neuroimaging, linkage disequilibrium in genetics, co-expression graph structures in omics, and group-level graph edge inference. He is also involved in developing machine learning models for individual-level inference, considering complex dependencies between high-throughput features. Dr. Chen has broad experience in collaborative biostatistical research, including clinical trials, environmental health, infectious disease, and cancer research.
Dr. Chen is also enthusiastic about fostering the next generation of statisticians and data scientists (see the Awards and Former Trainees sections below for recent awards won by trainees and the job placements of alumni).
