Ralph L. Nachman, M.D.
Dr. Ralph L. Nachman, the Lewis Thomas University Professor and Associate Dean of Clinical Research at Weill Cornell Medical College, is a physician, scientist, educator and administrator. Dr. Nachman has pioneered discoveries in hematology and medical oncology that have furthered the development of new clinical solutions to blood and vascular disorders.
In 1963, he began a more than 40-year career with New York Presbyterian Hospital and Weill Cornell Medical College, beginning as Director of Laboratories for Clinical Pathology, followed by his 25 years as Chief, Division of Hematology and Oncology and 17 years as Chairman of the Department of Medicine at Weill Cornell Medical College and Physician-in-Chief at New York Presbyterian Hospital.
Dr. Nachman has spearheaded multiple endeavors in biomedical research, clinical programs, educational curricula, residency training, fundraising, and quality assurance. His discoveries in vascular biology, and the establishment of the Specialized Center of Research (SCOR) in Thrombosis (National Institutes of Health) at New York-Cornell, led to his performing the first culture of human endothelial cells. This achievement initiated a modern explosion of knowledge in vascular biology. He has published numerous articles in the field of hematology and has lectured around the world. His honors include, The Stratton Award from the American Society of Hematology and the Robert Williams, MD Distinguished Chair of Medicine Award from the Association of Professors of Medicine. He is a member of the Institute of Medicine of the National Academy of Sciences.
