Research Abstract

My major research activities involve the design and analysis of clinical trials and the study of related statistical issues. As head of the Statistical Center for the Eastern Cooperative Oncology Group, I lead a group involved annually in the design and analysis of dozens of cancer clinical trials in most types of adult malignancies. These studies often include extensive biological correlative endpoints and quality of life evaluations in addition to primary efficacy evaluations. Some areas of current interest in statistical methodology include methods of adjustment for treatment noncompliance, design and analysis of studies with competing risks endpoints, dependent censoring related to incomplete follow-up of disease status, issues related to the interim analysis and monitoring of clinical trials, and analysis of high-dimensional laboratory data.
