Dr. Case obtained a PhD in Biostatistics from the University of North Carolina at Chapel Hill in 1987. He is currently a Professor of Biostatistics in the Department of Public Health Sciences at the Wake Forest University School of Medicine. He served as Director of the Biostatistics Core of the Comprehensive Cancer Center at Wake Forest University from 1991 to 2001, working actively with clinical, cancer control, and basic scientists in designing new studies and analyzing the resulting data. He served as a co-investigator for the FoCaS project, a study to develop, implement and evaluate a program designed to increase utilization of cervical and breast cancer screening among low income, low education, minority women, and he was the PI of the Biostatistics Core for the Breast Cancer Center of Excellence, a DOD funded longitudinal study examining menstrual bleeding and health related quality of life following the diagnosis and treatment of breast cancer, and the PI of the Statistical Center for the Ischemic Stroke Genetics Study, a case-control study assessing the associations between genetic factors and the risk of stroke. Dr. Case is currently the senior statistician for the Wake Forest University Cancer Research Base, a grant supporting the development of cancer clinical trials for use in the community.
Group Sequential Methods
Sample Size Determination
Analysis of Menstrual Bleeding Calendars
Dr. Case’s primary research interests are related to the design and analysis of clinical trials, particularly the development of new group sequential plans and the application of statistical methodology to cancer research. He is currently working on the development of phase II designs for time to event outcomes and methods for sample size determination, the analysis of survival data, and the analysis of menstrual bleeding data.
