Constantine Gatsonis has research interests in Bayesian inference and its applications to problems in biostatistics, medical technology evaluation with emphasis on the clinical evaluation of diagnostic imaging, bioinformatics with emphasis on proteomics, and methodologic aspects of health services and outcomes research.


Constantine Gatsonis, PhD, is Professor of Medical Science(Biostatistics) and Applied Mathematics and Acting Head of the Biostatics Section of the Department of Community Health. He joined the faculty 1995 and became the founding Director of the Center for Statistical Sciences. Dr. Gatsonis is a leading authority on the design and analysis of clinical trials of diagnostic and screening modalities and has extensive involvement in methodologic research in medical technology assessment and in health services and outcomes research. He is Group Statistician of the American College of Radiology Imaging Network (ACRIN), a NCI funded collaborative group conducting multi-center studies of diagnostic imaging and image-guided therapy for cancer. In his ACRIN work, Dr Gatsonis is the chief statistician of the Digital Mammography Imaging Screening Trial (a national study comparing digital to film mammography) and is also the chief statistician for ACRIN's arm of the National Lung Screening Trial (NLST). Dr Gatsonis was the lead statistician of the International Breast MRI Consortium and of the Radiologic Diagnostic Oncology Group (RDOG).

Dr. Gatsonis has served on numerous review and advisory panels, including the HSDG Study Section of the Agency for Health Care Policy Research, panels of the Center for Devices and Radiological Health of FDA, the Commission of Technology Assessment of the American College of Radiology, Data Safety and Monitoring Boards for NINDS and the VA, the Immunization Safety Review Committee of the Institute of Medicine. He is a member of the steering group of the STARD project (Standards for Reporting of Diagnostic Accuracy), which recently published the first comprehensive checklist for reporting the results of diagnostic test evaluations. He is also co-convenor of the Screening and Diagnostic Tests Methods Working Group of the Cochrane Collaboration and a member of the steering group of the Cochrane Diagnostic Reviews initiative, which is developing the methodologic and organizational infrastructure for the inclusion of systematic reviews of diagnostic accuracy in the Cochrane Library.
Dr. Gatsonis is the founding editor-in-chief of Health Services and Outcomes Research Methodology and serves as a deputy editor of Academic Radiology and a member of the editorial board of Clinical Trials . Previous editorial experience includes membership of the editorial board of Statistics in Medicine , and Medical Decision Making .

Dr Gatsonis was elected fellow of the American Statistical Association and the Association for Health Services Research.
