Mark Kozak

Mark Kozak, MD is a Professor in the Department of Medicine at Pennsylvania State University's College of Medicine, specializing in the Division of Cardiology and Penn State Heart and Vascular Institute. His clinical work focuses on cardiovascular disease, internal medicine, and interventional cardiology with expertise in structural heart disease and transcatheter procedures.

Dr. Kozak completed his medical education at Johns Hopkins University School of Medicine (1984), followed by an internal medicine residency at Johns Hopkins Hospital (1987), and a cardiology fellowship at University of Utah Hospital and Clinics (1993). His research spans interventional cardiology techniques, structural heart interventions, and cardiovascular outcomes.

His scholarly work demonstrates consistent publication output since 1995, with recent emphasis on transcatheter aortic valve replacement, percutaneous coronary interventions, and complications analysis of cardiac devices. The research integrates clinical trials, registry analyses, and technical innovation in catheter-based procedures, contributing significantly to evidence-based practices in interventional cardiology.

• American College of Cardiology/Merck Adult Cardiology Research Fellowship (1992-1993)
• Teaching Attending of the Year, Cardiology (1996)
