Research Interests

My research interests include the design and analysis of clinical trials, methods for exploratory analysis of survival data and adaptive non-parametric regression. I also work on new methods for analyzing genomic data.

Most of my collaborative research focuses on the design, analysis and conduct of therapeutic clinical trials. I lead the statistical activities related to Phase II and Phase III clinical trials in lymphoma for the Southwest Oncology Group (SWOG) for the SWOG Statistical Center. Currently I am investigating design and analysis methods for targeting patient subgroups appropriate for both Phase II and Phase III clinical trials.

I am also a Research Professor at the University of Washington, Department of Biostatistics.
