Research Focus
Dr. Witschey's lab at the University of Pennsylvania focuses on understanding and improving treatments for heart problems, especially those caused by blockages in blood flow. They care deeply about identifying ways to detect and analyze damage that occurs after blood flow is restored to the heart, which can paradoxically cause additional harm. Through advanced imaging techniques, the lab aims to study ‘reactive oxygen species’ that help track the heart's recovery process after a heart attack, ultimately enhancing clinical outcomes for patients.

Research Aims
3AIM 01Investigate the link between reactive oxygen species and iron levels in heart tissue using non-invasive imaging methods.
AIM 02Assess the severity of heart injury related to reactive oxygen species in patients post-infarction.
AIM 03Examine how imaging markers relate to long-term heart remodeling after an injury.
