Research Interests

Dr. Jianrong (John) Wu's research centers on the statistical design and data analysis for Therapeutics of Solid Tumor Program (TSTP) and Pediatric Pre-Clinical Testing Program at St Jude.

My primary research interest is to develop new methodology for designing clinical trial and pre-clinical study. Pediatric cancer clinical trial is often conducted as a single-arm phase II trial or a randomized phase III trial with time-to-event endpoint, particular with a proportion of patients cured. Statistical methodology for such trial design is relatively scarce. My research is to provide more flexible and powerful statistical design for such trials. For pediatric pre-clinical tumor xenograft model, my research interest is to develop new methodology to assess the anti-tumor activity of the treatment for single drug testing and to assess the synergism for drug-drug combination testing. My other methodology research interests are survival data analysis, randomized phase III survival trial design and group sequential trial design and likelihood-based small sample and large sample inference.
