Personal Statement

My primary research interest is the design, implementation and analysis of phase II and III clinical trials for cancer research.  My work with the NRG Oncology clinical trials group has included trials evaluating therapies for the treatment of colon, rectal, and breast cancer.  The focus of my methodological research has been the development of statistical methodologies for identifying a subset of a clinical trial population where a treatment is effective.

 I am one of the Primary Investigators for the NRG Oncology Statistics
and Data Management Center - a clinical trials research group comprising
200+ employees.  I am responsible for
oversight of the statisticians supporting the scientific committees of NRG
