Mihriye Mete, PhD

Mihriye Mete, PhD, is the Biostatistics Manager in the Department of Biostatistics and Epidemiology at MedStar Health Research Institute (MHRI) and an Associate (Research) Professor in the Department of Psychiatry of Georgetown University School of Medicine. Dr. Mete, an expert in numerous statistical software applications including Stata, SPSS and R, specializes in quantitative research methods and study design. With her interdisciplinary background, she is able to view clinical studies from the public health, policy, and socio-economic perspectives, among others, and incorporate the most appropriate and scientifically sound study design and data analysis approaches.

Dr. Mete has extensive collaboration experience and routinely assists researchers in the development and management of quantitative interdisciplinary research. Specifically, she develops proposals, analyzes data, and assists with manuscript preparation and submission. As a result of her reputation for designing scientifically sound studies and her ability to develop feasible specific aims, she often is asked to provide critical feedback as a reviewer for studies designed by other researchers. Because of the collaborative nature of her work, she has experience working with numerous investigators across a broad range of disciplines and has co-authored several peer-reviewed manuscripts. Her work is widely published in journals, such as the Journal of the American Medical Association, the Journal of Diabetes and Its Complications, and the Journal of Traumatic Stress.

In addition to her research and management responsibilities, Dr. Mete serves as a consultant in econometric and demographic analysis and has worked for such notable organizations as the World Bank. Prior to joining MedStar, she held faculty positions at Michigan State University and the University of Georgia and was a visiting Assistant Professor at the Georgetown Public Policy Institute, where she taught courses in advanced statistical methods.

Dr. Mete earned a bachelor's degree in Management Engineering, with a specialization in Economics and Mathematics, from Istanbul Technical University and received a PhD in Political Science, with emphasis on statistical methods, from the State University of New York at Stony Brook. She has additional formal training in Bayesian analysis, Bootstrapping methods, and Epidemiology and is an active member of the American Statistical Association.

Nawar Shara, PhD

Nawar M. Shara, PhD, is director, Department of Biostatistics and Bioinformatics, MedStar Health Research Institute (MHRI); director, Biostatistics Core, Georgetown-Howard Universities Center for Clinical and Translational Science; and associate professor of Medicine, Division of Endocrinology, Georgetown University. Dr. Shara is an established, NIH-funded, clinical investigator with many years of experience overseeing statistical and data management activities for large, multi-center clinical trials. Within MHRI, she manages a department of PhD- and master's-level associates.

Dr. Shara has served as principal investigator, sub-investigator, and lead biostatistician on numerous studies and clinical trials. Her expertise is in the design and analysis of large-scale epidemiological trials, specifically in the development of novel statistical methodologies, such as adaptive dosage-finding techniques, imputation methods and predictive analytics for big data. In addition, she has been developing tools to extract electronic health records data for use in research to improve patient outcomes.

Her research has focused on developing novel statistical methodologies to investigate correlates of kidney and cardiovascular disease and to identify non-traditional predictors of these diseases. She has authored or co-authored nearly 50 publications in peer-reviewed journals, such as the American Journal of Kidney DiseasePlos One, and the International Journal of Stroke. She is a member of the American Statistical Association, the Royal Statistical Society, the American Society of Nephrology, and the Women in Statistics Caucus. She serves as chair of the Science and Research Committee for the National Arab American Medical Society.

Dr. Shara obtained undergraduate and graduate degrees at Damascus University, Damascus, Syria, and a master's degree and PhD from American University in Washington, DC.
