Gregory Tasian MD, MSc, MSCE

Faculty Member

Gregory Tasian is an associate professor of urology and epidemiology and a senior scholar in the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania Perelman School of Medicine. His clinical practice and research program are based at Children’s Hospital of Philadelphia (CHOP), where he has faculty appointments at PolicyLab, the Division of Urology and the Center for Pediatric Clinical Effectiveness.

He is a practicing pediatric urologist with a clinical focus on kidney stone disease, and is surgical director of the Pediatric Kidney Stone Center at CHOP. His research, which is supported by National Institutes of Health/National Insitute of Diabetes and Digestive and Kidney Diseases and Patient-Centered Outcomes Research Institute, is devoted to decreasing the lifetime burden of kidney stone disease, with a particular emphasis on clinical trials of interventions to improve health behaviors to decrease kidney stone recurrence, comparative effectiveness of surgical interventions for kidney stones, the temperature-dependence of nephrolithiasis and understanding the role of the gut microbiome in kidney stone disease.

Dr. Tasian is one of the lead investigators on PolicyLab’s COVID-19 forecasting model, known as “COVID-Lab: Mapping COVID-19 In Your Community,” which tracks coronavirus transmission and test positivity rates across all U.S. counties, and projects cases counts for more than 800 counties with active outbreaks. Dr. Tasian and his collaborators have received national attention for this unique project, which they have used to advise the White House Coronavirus Task Force, governors, state public health officials and Philadelphia leaders on emerging hotspots and local strategies for reducing the spread of the virus.

He also has an active research program in applying machine learning to extract informative features from diagnostic imaging and other complex data to risk stratify and predict outcomes for children and adults with benign urologic disease.
