Dr. Jorge L. Sepulveda, M.D., Ph.D, Advisory Board Member
Dr. Sepulveda is a Professor of Clinical Pathology and Cell Biology at Columbia University College of Physicians and Surgeons and currently serves as the Associate Director for Laboratory Medicine and Medical Director of Laboratory Informatics at Columbia / New York Presbyterian Hospital in New York, NY. As a clinical laboratorian and research scientist, his specialty focuses on using large-scale data analysis and computational approaches to understand and guide efficient use of clinical laboratory test to improve patient care.
After earning his PhD in Cell and Molecular Biology from the Baylor College of Medicine in 1994, Dr. Sepulveda went on to complete an MD at the University of Lisbon in 1984. His current research centers on Systems Biology approaches to understanding molecular mechanisms regulating cellular phenotypes, in particular focusing on the transformation from a physiologic to a pathologic state. A particular angle of interest is the integration of large scale genomic, transcriptomic, epigenetic, proteomic, and metabolomic data to derive a molecular “holistic” approach to understanding the development of gastro-intestinal cancers (particularly of the esophagus and stomach) and in a separate project, the transition from a healthy heart to cardiac hypertrophy and heart failure. The aim of this research is for a comprehensive, integrated view of pathology to develop personalized diagnostic, prognostic, and therapeutic approaches to disease.
