Sato, Thomas N
 (212) 746-6161 
Following a very brief postdoctoral training at Scripps (La Jolla, CA), in January, 1991, Tom Sato began his own laboratory as an Assistant Member at the Roche Institute of Molecular Biology. Roche Institute was a basic science institute funded by Roche, the same arrangement as another world renowned institution, Basel Institute of Immunology, had. At the Roche Institute, all the members were able to pursue the most creative and challenging areas of life science with no need to write grants. At the Roche Institute, Tom began his initial quest to discover the essence of vascular development.
As a graduate student at Georgetown and a postdoctoral fellow at Scripps, Tom studied molecular and biochemical mechanisms of neurotransmission and neural development. However, in the middle of graduate training, Tom realized that he will not be able to understand the essence of "Mind" through molecular biological approaches. Therefore, Tom has decided to apply his training in molecular biology and biochemistry to a more tractable subject: vascular development.
As soon as he began his small group at the Roche Institute, he began identifying molecules that may play one of the most essential roles in vascular development. As a result, Tom and his group has identified a new class of receptor tyrosine kinases, Tie1 and Tie2, that play one of the most profound roles in vascular development 1-5.
At the closure of the Roche Institute, Tom moved to Harvard Medical School/Beth Israel Deaconess Hospital in 1995. During his brief tenure there, he and his group collaborated with George Yancopoulos's group at Regeneron Pharmaceuticals to characterize a family of ligands for Tie receptors 6-8.
In 1997, Tom moved to the University of Texas Southwestern Medical Center at Dallas, Texas. He stayed there as Associate Professor and then as Full Professor until 2004. In Texas, Tom and his group continued to identify various novel mechanisms for vascular development and differentiation, and also began a few new lines of research areas 9-19. Tom considers this period of time in Texas a "rejuvenation" period for his career.
In January, 2005, Tom moved to Weill Medical College of Cornell University, in New York City. After several years of "hibernation" period, he is now re-born and ready for new challenges in one of the most exciting, artistic, and philosophical places in the world, New York City. At Cornell, Tom investigates several scientific questions that have the most profound and long-lasting impacts on human life, philosophy and medicine.
