Biography

Dr. Zhang joined UT Southwestern as an assistant professor in September, 2007. He previously was a postdoctoral fellow at the University of Texas M.D. Anderson Cancer Center.

Dr. Zhang’s research interest in statistical methodology lies in two main areas: Bayesian hierarchical modeling and clinical trial design. He has published multiple papers on the application of Bayesian hierarchical models to disease mapping, joint modeling of longitudinal and survival outcomes, item-response theory for grant review, functional enrichment analysis to detect important pathways, and multi-level modeling to detect factors that impact cancer screening, etc. Another area of his research interest is design methodology for clinical trials to account for various pragmatic issues such as correlated outcomes (clustered and longitudinal), missing data, small sample sizes, historical control, random variability in cluster size, and cost constraints, etc. He has published multiple high quality papers in this area and in 2015 he co-authored a book titled “Sample Size Calculations on Clustered and Longitudinal Outcomes in Clinical Research” (Chapman & Hall, New York). Dr. Zhang has been successful in securing extramural grants as the PI to support his independent research program: an NIH R03 grant to conduct secondary data analysis on VA HIV registry in 2012; an NSF grant to build risk prediction model based on electronic health record data in 2013; and a PCORI methodology development grant to address pragmatic design issues in stepped-wedge cluster randomized trials in 2017.
