Ying Ding, PhD

My primary research interests include semiparametric methods and inferences, especially for time-to-event data; subgroup analysis such as simultaneous inference and biomarker/subgroup identification. Currently, my collaborative research focuses on proteomic experiment design, network analysis for psychiatric disorders and progression analysis of AMD (Age-related Macular Degeneration).
