Overview
Current projects include:
- evaluating type 2 acute myocardial infarction in older adults as a candidate geriatric syndrome
- identifying post-discharge characteristics associated with optimal patient-centered outcomes among older adult survivors of acute myocardial infarction
- evaluating functional and cognitive sequelae of COVID-19 among older adults
- investigating drivers of physician-scientist professional identity formation among U.S. medical students
