Dr. Rosen is a Member in the Department of Medicine and in the Molecular Pharmacology and Chemistry Program at Memorial Sloan-Kettering Cancer Center, where he serves as Head of Developmental Therapeutics. He is also a Professor of Pharmacology, Cell Biology and Medicine at Cornell University Medical School.

His major interests include the study of key molecular events and growth signaling pathways responsible for cancer development and the use of this information for developing mechanism-based therapeutic strategies. He played an important role in the development of tyrosine kinase-mediated signaling inhibitors, having pioneered the concept that cancer cells are dependent on cellular machinery for protein folding.

Dr. Rosen received his undergraduate degree in chemistry from Columbia College and an M.D. and Ph.D. in molecular biology from the Albert Einstein College of Medicine. He completed postdoctoral training and a fellowship in medical oncology at the National Cancer Institute. He was on the senior staff of the Medicine Branch at the NCI prior to joining the faculty of Memorial Sloan-Kettering Cancer Center.
