James J. Dignam, PhD

Dr. Dignam's primary research involves the design, conduct, and analysis of cancer clinical trials, including early development (phase I), pilot efficacy and safety (phase II), and definitive evaluation (phase III) trials. He is the Executive Director of the Statistics and Data Management Center for NRG Oncology, a National Cancer Institute sponsored multi-center clinical trials group with over 500 recruitment sites in North America and beyond and over 100 active clinical trials. Dr. Dignam's methodology interests include trial monitoring and early stopping rules, competing risks, hazard function estimation, and prognostic modeling. He also has engaged in and led investigations into sociodemographic factors such as race/ethnicity and BMI/obesity on cancer prognosis and treatment response. Courses taught include introductory biostatistics, clinical trials, survival analysis, and regression modeling methods.
