Ananda Sen

Ananda Sen, PhD

  • Lee A. Green Collegiate Research Professor, Department of Biostatistics
  • Research Professor, Department of Family Medicine

Dr. Sen holds research professor titles in the departments of Family Medicine and Biostatistics. He is a fellow of the American Statistical Association and an elected member of the International Statistical Institute. He is a past recipient of the Teaching Excellence Award at the School of Public Health. He has an established career record as a statistician with over 180 publications in peer-reviewed journals and invited book chapters. He has methodological expertise in survival analysis, Bayesian methods, and correlated agreement, topics which have a range of applications in bio-medical Sciences. Dr. Sen has extensive collaborative experience in cancer prevention and biomarker research with diet and disease endpoints. In the past, he has served as the director of the Biostatistics Core in the NCI funded Specialized Program on Research Excellence in GI Cancer at the University of Michigan. He serves as the Book Review Editor for the journal International Statistical Review. He has multiple editorial commitments, serving as editorial board members of Computational Statistics and Data Analysis, International Statistical Review, and Communications in Statistics, and as the statistics co-editor for the American Journal of Preventive Medicine. He has been involved in writing practice guidelines for the Committee on National Statistics (CNSTAT), in the National Academy of Sciences, and for the Society for Integrative Oncology.

Research Interests:
My primary focus of research is in survival analysis with an emphasis on competing risks and recurrent events. In general, I am interested in implementing Bayesian models and methodologies in biomedical applications that range from cancer clinical trials to genetic applications and sparse data. A more recent methodological focus is on analyzing correlated agreement measures that have immense applications in diagnostic testing.

Research Projects:
As a joint faculty in Michigan Medicine, I am heavily involved in collaborative projects in a variety of topics including cancer prevention through behavioral and lifestyle interventions, health services research, women's health, disability research. My applied collaborations as a primary biostatistician supporting the work of the GI oncology group at the University of Michigan Rogel Cancer Center have focused on studies of biomarker discovery and dietary interventions in gastrointestinal cancers.
