Dr. Gelb’s career embodies a deep commitment to unraveling the complex genetic architecture underpinning congenital heart disease (CHD), a leading cause of morbidity and mortality in children worldwide. His comprehensive research portfolio bridges the clinical and molecular domains, illuminating genetic variants responsible for CHD and associated developmental syndromes. Over decades, his laboratory at Mount Sinai has leveraged high-throughput sequencing technologies, genomics, and rigorous phenotypic characterization to decode the multifactorial etiology of these disorders, shifting paradigms within pediatric cardiology and genetic medicine.

A faculty member at Mount Sinai since 1991, Dr. Gelb has been instrumental in cultivating an international reputation for genomic discovery in pediatric populations. His work notably advances understanding of Noonan syndrome and related RASopathies—a cluster of disorders caused by mutations affecting the RAS-MAPK signaling pathway, which regulates cellular proliferation, differentiation, and apoptosis during embryogenesis. These insights have significant clinical implications, improving diagnostic precision and offering potential therapeutic targets for these previously enigmatic conditions.

Among his many contributions, Dr. Gelb co-led a groundbreaking study elucidating gene-pair interactions responsible for digenic inheritance in CHD. This revelation expands the genetic paradigm beyond monogenic models, illustrating how the concomitant inheritance of variants in two genes synergistically disrupts normal heart development. The application of advanced bioinformatics and integrative genomic approaches in this research has paved new avenues for tailored genetic counseling and personalized medicine strategies for affected families.

Beyond his research, Dr. Gelb’s leadership at the Mindich Child Health and Development Institute has established a multidisciplinary hub where genetics, artificial intelligence, clinical trials, and health services research converge.
