Every successful clinical trial is a dynamic collaboration between the scientist and the biostatistician. In this episode with Dr. Fang-Shu Ou, she explains the role that a biostatistician plays in the life of a study. Dr. Ou is a Mayo Clinic biostatistician and the faculty statistician for the Alliance for Clinical Trials in Oncology, leading several gastrointestinal phase 3 clinical trials that aim to improve patient care. Dr. Ou is also the group statistician for ACCRU (the sponsor of this podcast), the cancer research network. Her research interest is in survival analysis, with the goal of developing new statistical methods for clinical trial design and analysis and assimilating these new methods into practice.
