Siddharth Roy, Ph.D., M.S.

Siddharth Roy, Ph.D., M.S., joined the Biostatistics Branch (BB) as a predoctoral fellow in September 2019. He received an M.S. in statistics from North Carolina State University, where he spent several years performing genomic data analysis. Dr. Roy completed his Ph.D. in statistics from the University of Maryland, Baltimore County in 2023. His dissertation research improved the modeling flexibility to study the relationship between longitudinal biomarkers and time-to-cancer outcomes motivated by cervical pre-cancer. His approaches make it easier to include multiple longitudinal biomarkers of mixed type for joint models with interval-censored outcomes and allow for dynamic risk prediction for both early detection and long-term risk. He became a postdoctoral fellow in 2024.

As a postdoctoral fellow, Dr. Roy continues to work under the mentorship of Danping Liu, Ph.D. His research focuses on developing methods for identifying longitudinal biomarkers for time-to-cancer outcomes in high-dimensional settings.
