Ph.D., Cornell University, Biometry, 1990.
My statistical methods research, in conjunction with colleagues and students, aims to improve the design and analysis of disease prevention trials, and observational studies. One emphasis has been the development of efficient design and analysis strategies for group randomized trials. Recent efforts include the proposal of a weighted permutation inference and a global test for multiple endpoints. Another emphasis has been the development of methods for cancer biomarker studies. Recent efforts include the development of guidelines for biomarker evaluation in cancer early detection, analysis methods for high dimensional data such as protein expression data from mass spectrometry, and Finite Mixture Models.
My applied research, in conjunction with colleagues and staff members, include the coordination of the national Early Detection Research Network (EDRN). This network includes 31 institutions in US with the mission to identify and validate biomarkers for early detection of cancer. We at FHCRC provide logistic, bioinformatics, and data management support for EDRN, and develop statistical methodology useful for EDRN mission.
I also collaborate with a large number of colleagues on variety of research projects including prostate cancer epidemiology and outcome, GI cancer etiology and biomarkers, community intervention trials, and occupational epidemiology.
