Dr. Brent Logan joined the Division of Biostatistics in the Summer of 2001. He has methodological research interests in multiple comparison procedures, clinical trial design, and survival analysis. Research in multiple testing includes methods for analyzing multiple endpoints in clinical trials, analysis of dose-response studies, and multiplicity adjustment in functional MRI studies. His interests in clinical trial design include randomized phase 2 clinical trials and biologic assignment trials in bone marrow transplant studies. Recent work in survival analysis has focused on inference for competing risks and multistate models using pseudo-value regression, analysis in the presence of crossing survival curves, and methods for the analysis of complex bone marrow transplant data. He is a biostatistician for the Blood and Marrow Transplant Clinical Trials Network (BMTCTN) and the Center for International Blood and Marrow Transplant Research (CIBMTR), as well as a statistical consultant for the National Marrow Donor Program.
