Research and Professional Experience

Dr. Jaar is interested in the conduct of epidemiologic studies in the field of end-stage renal disease and its related complications. His personal research interest is currently focused on outcome studies of peripheral arterial disease (PAD) in end-stage renal disease (ESRD) patients and morbidity and mortality of ESRD patients by dialysis modality. In addition to leading the Cardiovascular Endpoint Committee of the CHOICE study, he is involved in several research projects within the Division of Nephrology and also at the Welch Center for Prevention, Epidemiology and Clinical Research, and the Department of Environmental Health at the School of Public Health.
