Summary
- Jirair K. Bedoyan, MD, PhD, FACMG is Professor of Pediatrics at the University of Pittsburgh School of Medicine in the Division of Genetic and Genomic Medicine. He also is Program Director of the Clinical Biochemical Genetics Fellowship at UPMC Children’s Hospital of Pittsburgh; Director of Medical Genetics Clinical Research in the Division of Genetic and Genomic Medicine at UPMC Children’s Hospital of Pittsburgh; University of Pittsburgh IRB Committee member; and currently serves on the United Mitochondrial Disease Foundation Scientific and Medical Advisory Board.
Dr. Bedoyan is a clinical and biochemical geneticist investigating the genetics and pathophysiology of several inborn errors of metabolism and mitochondrial disorders including disorders of pyruvate metabolism, particularly mitochondrial pyruvate dehydrogenase complex deficiency (PDCD) and pyruvate carboxylase deficiency (PCD). He has published over 50 articles, reviews, and book chapters. He has an active clinical research program, with government-funded and industry-sponsored clinical studies/trials. Bedoyan served as project co-PI (2014-19) and PI (2019-25) on NIH-funded U54 Rare Disease Clinical Research Network, North American Mitochondrial Disease Consortium (NAMDC) project grants with focus on mitochondrial PDCD, and received pilot grants for clinical research from the Urea Cycle Disorders Consortium and NAMDC. His work is also supported by philanthropy funds from the Elizabeth Watt PDCD Research Fund and the Noelle and Nicholas Thoma Fund for Congenital Lactic Acidosis. Bedoyan has achieved local, national, and international recognition for excellence in patient care and for his novel scholarly work to improve patient care and health outcomes for several complex inherited disorders of energy metabolism including PDCD and PCD.
