Peter J. Gruber

Peter J. Gruber is Professor of Surgery at the Yale School of Medicine and Chief of Pediatric Cardiac Surgery at Yale New Haven Children’s Hospital. He also serves as Vice Chair for Research in the Department of Surgery, leading both clinical and scientific initiatives in congenital heart disease.

Education:

• B.A. in Biochemistry, University of Pennsylvania (1985)
• M.D., University of Pennsylvania School of Medicine (1992)
• Ph.D. in Biochemistry and Biophysics, University of Pennsylvania (1992)
• Postdoctoral Fellowship, American Heart Association-Bugher Foundation Center for Molecular Biology, UCSD (1994–1996)
• Clinical Training: Johns Hopkins Hospital (General and Cardiothoracic Surgery), The Children’s Hospital of Philadelphia (Pediatric Cardiothoracic Surgery)

Research Interests:

Dr. Gruber’s research focuses on the molecular and genetic basis of congenital heart disease. His lab investigates epigenetic regulation—particularly the role of histone deacetylases (HDACs)—in cardiac development and ischemic injury. His team also studies ventricular maturation and uses induced pluripotent stem cells (iPSCs) to model patient-specific cardiac conditions. By integrating genomics, stem cell biology, and animal models, his work aims to uncover novel therapeutic targets for congenital and acquired heart diseases.

Publication Trends:

His recent publications emphasize large-scale genomic studies of congenital heart disease, including dominant and recessive genetic contributions and pathway analysis (e.g., NOTCH signaling). He also contributes to clinical outcomes research in heart transplantation and innovative surgical techniques, reflecting a strong translational focus from bench to bedside.

Scientific Awards:

• Member, American Society for Clinical Investigation
• Member, American Surgical Association

Advising and Grants:

While specific students are not listed, Dr. Gruber leads the Gruber Lab and mentors trainees in cardiovascular research. He has secured significant research funding, including a recent $2 million NIH grant for engineering heart conduits. He is Principal Investigator on multiple clinical trials, including the CorMatrix Cor TRICUSPID ECM Valve Replacement Study, demonstrating sustained grant support and leadership in translational research.

Labs and Teams:

He leads the Gruber Lab, which is part of the Department of Surgery at Yale. His research is conducted in collaboration with the Adult Congenital Heart Program, Children’s Heart Center, and Fetal Care Center. He works with multidisciplinary teams involving geneticists, cardiologists, bioengineers, and surgeons to advance understanding and treatment of congenital heart defects.
