Ravi Iyengar, is a systems biologist and principal investigator of the NIGMS-funded Systems Biology Center New York at The Mount Sinai Medical Center.[1][2]
Trained as a biochemist, Iyengar studies cellular signaling networks using both experiments and computer simulations. His laboratory focuses on how cell signals are routed and processed through cellular signaling networks within cells to discover new drug targets for complex diseases.[3][4][5] He has published more than 100 primary papers, 92 reviews and is the editor of 6 books.
Biography
Iyengar earned both an undergraduate degree in Chemistry and Physics in 1971 and a master's degree in Biophysics in 1973 from the University of Mumbai in India. He completed his Ph.D. in Biophysical Sciences at the University of Houston in 1977. He joined Baylor College of Medicine in 1977 as a postdoctoral fellow and rose to assistant and then associate professor. In 1986, he joined the Department of Pharmacology at The Mount Sinai Medical Center as an associate professor. In 1999, he was appointed chairman of the Department of Pharmacology at Mount Sinai, and in 2001 he was named Mount Sinai's Dorothy H. and Lewis Rosenstiel Professor and chair of the Department of Pharmacology and Biological Chemistry. He stepped down from his position as chair in January 2014.
Iyengar served as the dean of research for The Mount Sinai School of Medicine from 2002 to 2004.
In 2004, Iyengar was elected fellow of the American Association for the Advancement of Science.[6] Additional honors include:
- Established Investigator, American Heart Association, 1980–1983
- New Investigator Award, NIH, 1978–1980
- National Research Service Award, NIH
Iyengar holds Patent No. 20080261820: Methods to Analyze Biological Networks.[7]
