Jarrod Dalton Research Program

Research

Dr. Dalton has conducted National Institutes of Health-funded population health research continuously since 2013, including a National Institute on Aging-funded collaboration between Cleveland Clinic and MetroHealth System to understand neighborhood-level variation in cardiovascular risk. He also co-leads an National Heart, Lung, and Blood Institute-funded project to develop more equitable policies for lung transplant allocation through the application of robust statistical and simulation-based modeling approaches.  Dr. Dalton has over 100 peer-reviewed scientific articles, and is a member of the editorial board for Medical Decision Making. His scientific contributions have earned the designation of Top-Ranked Abstract at 3 recent Annual Meetings of the Society for Medical Decision Making (SMDM). He received the 2018 SMDM Outstanding Paper by a Young Investigator Award for his Annals of Internal Medicine article.
