Alvaro Rojas-Pena, M.D.
Research Investigator, Lab Coordinator 


Alvaro Rojas-Pena, M.D. is a Research Investigator in the Department of Surgery, at the University of Michigan Medical School in Ann Arbor, Michigan. Dr. Rojas' research interests focus on the perservation of organs from transplantation as well as increasing the viability of donor organs following cardiac death.

Jonathan W. Haft, M.D.
Associate Professor of Surgery


 Dr. Haft is the director of the Extracorporeal Life Support Program, replacing the legendary program founder, Dr. Robert Bartlett. His interests include the use of mechanical circulatory support for heart failure and shock, critical care, and heart transplantation. Additionally, he is the associate director of the Cardiovascular Intensive Care Unit at the University of Michigan Cardiovascular Center and he is the division chief of Cardiothoracic Surgery at the Ann Arbor Veterans Affairs Hospital.

Ronald B. Hirschl, M.D.
Professor of Surgery, Section Head Pediatric Surgery

Dr. Hirschl's areas of interest and expertise are in the management of the critically ill patient, especially in the treatment of pediatric and adult respiratory failure through the application of extracorporeal life support (ECLS, ECMO), liquid ventilation, and the implantable artificial lung. Dr. Hirschl is also the Chairman of the Steering Committee of the Extracorporeal Life Support Organization (ELSO).

William R. Lynch, M.D.
Associate Professor of Surgery

Dr. Lynch's research focus is ex vivo lung perfusion and other means of advanced donor organ management.  In addition Dr. Lynch conducts investigations in ECMO and critical care.

Mark Meyerhoff, Ph.D.
Philip J Elving Collegiate Professor of Chemistry and Professor of Chemistry


Mark Meyerhoff, Ph.D. is a Professor in the Department of Chemistry at the University of Michigan. Dr. Meyerhoff's research interests include: 1) the design and study of novel electrochemical and optical chemical sensors based on thin polymeric films doped with selective host compounds (especially metal-ligand complexes); 2) the synthesis, characterization and biomedical applications of polymeric materials that release/generate nitric oxide (NO); and 3) development of novel non-separation immunoassay methods.


George B. Mychaliska, M.D.
Professor of Surgery

Dr. Mychaliska's clinical areas of interest and expertise are prenatal diagnosis and fetal surgery. Dr. Mychaliska's research interests include prenatal diagnosis and therapy, pulmonary development, and congenital diaphragmatic hernia.

Robert W. Neumar, M.D., Ph.D.
Professor and Chair, Emergency Medicine 

Dr. Neumar's research interests focus on understanding the mechanisms of brain injury, and development of therapies to minimize brain damage and improve the brain's ability to recover after cardiac arrest and traumatic brain injury.


Gabe E. Owens, M.D., Ph.D
Assistant Professor, Department of Pediatrics and Communicable Diseases 

Dr. Owens' clinical areas of interest and expertise are in pediatric cardiac critical care.  His research focuses on the development of novel therapeutic interventions for treatment of congenital heart diseases, an artificial placenta for premature infants, and a technique to optimize heart preservation for cardiac transplantation.

Kagan Ozer, M.D.
Clinical Associate Professor, Department of Orthopaedic Surgery
Dr.  Ozer's research interests include management of complex hand and upper extremity trauma, nonunions, and peripheral nerve injuries.  Dr. Ozer conducts experimental research on ischemia-reperfusion injury and composite tissue allograft transplantation. 

Joseph A. Potkay, Ph.D.
Adjunct Research Investigator, Department of Surgery
Research Bioengineer, VA Ann Arbor Health System
Dr. Potkay's research focuses on a unique approach to the improvement of membrane lung efficiency.  This has been a goal for decades but has never been realized and Dr. Potkay's research has potential to solve these problems. 

 Jeffery D. Punch, M.D.
 Professor of Surgery

Jeffrey D. Punch, M.D. is an Associate Professor of Surgery in the Division of Transplantation in the Section of General Surgery. Dr. Punch received his medical degree from the University of Michigan. His clinical interests include immunosuppression management of liver transplant recipients, acute liver failure, and liver transplantation in children. In addition to a clinical practice, Dr. Punch also runs numerous clinical research studies involving transplant recipients.
