About Us

Whether we are caring for our patients, conducting research, or educating medical students, residents, and fellows, our number one priority is to advance the understanding and prevention of cardiovascular disease.

Clinical Care

Our faculty and staff treat patients at Michigan Medicine's Frankel Cardiovascular Center - one of the largest facilities in the heart of the University of Michigan Medical Campus. It is in this 350,000 square-foot, multidisciplinary facility that we can fulfill our vision of being the best academic heart and vascular center in the world. 

The facility, which opened June 11, 2007, includes a 24-bed surgical post-procedure ICU, 24 vascular general/moderate care beds, nine cardiac procedure rooms, four cardiac surgery operating rooms, two vascular surgery operating rooms, two general thoracic operating rooms, two endovascular procedure labs, and 36 clinic exam rooms.


Our faculty have made groundbreaking contributions to the prevention and treatment of heart disease. Our research efforts span a broad spectrum of basic, translational, and clinical research activities.

Basic and Translational Research

Our strengths in basic and translational research include:

  • Arrhythmia
  • Cardiac Myocyte Biology
  • Cardiovascular Biomechanics
  • Cardiovascular Genetics
  • Tissue and Cell Regeneration
  • Vascular and Thrombosis Biology

Clinical Research

We are actively involved in clinical research. New medications, devices, surgical procedures, diagnostic tools and prevention strategies need thorough testing before they can become part of routine patient care. We are involved in numerous clinical trials that span our clinical areas. 

Education and Training

It is our duty to pass the torch of knowledge on to the next generation and also to share with healthcare professionals around the world what we have learned in the clinic and research lab to further the prevention and treatment of cardiovascular disease.  

Our Fellowship Programs offer comprehensive educational curriculum designed to train future leaders in the field of cardiovascular disease. In addition, we offer a variety of continuing medical education courses and seminars taught by our faculty.
