Associate Professor of Epidemiology (Research)


Dr. Gareen has been a member of the faculty of Brown’s Center for Statistical Sciences since 1999.  She is an epidemiologist with over a decade of experience in the collaborative design and conduct of studies of diagnostic imaging technologies.  Her research focuses on patient outcomes associated with diagnostic imaging technologies, including the impact of imaging on patient health, patient quality of life, and medical care utilization.  One of the patient outcomes of particular interest to Dr. Gareen is the impact of significant incidental findings (SIFs) on patient health and medical care utilization.  As Co-Chair for the American College of Radiology Imaging Network (ACRIN) 6654 National Lung Screening Trial (NLST), Dr. Gareen was a key member of the NLST Executive Committee responsible for day-to-day operation of the trial, as well as for publication and dissemination of the primary trial results.  Dr. Gareen was also responsible for overseeing the collection of information on outcomes and health care utilization from the medical records and the endpoint verification process in the ACRIN arm of the trial.  As a co-investigator on the Grand Opportunity grant Comparative Effectiveness of Advanced Imaging in Cancer, Dr. Gareen is examining the effect of SIFs on Medicare costs following lung screening. She has also provided methodologic leadership for the design, development, and implementation of a study examining the incidence and significance of extracolonic findings (SIFs) in the National CT Colonography Trial.
