Rangaswamy Srinivasan

from Wikipedia, the free encyclopedia

Rangaswamy Srinivasan (born February 28, 1929 in Madras ) is an Indian-American physicist, inventor and entrepreneur.

Srinivasan studied chemistry at the University of Madras (B.Sc. in Chemistry, M.Sc. in Physical Chemistry). In 1953 he came to the USA as a graduate student and received his Ph.D. at the University of Southern California with a dissertation on protein chemistry with Sidney Benson . As a postdoctoral fellow he worked at the California Institute of Technology in 1956 and at the University of Rochester from 1957–61 . 1961–1990 he led a group at the IBM Thomas J. Watson Research Center in Yorktown Heights , NY. Since 1990 he has headed UVTech Associates , a company he founded , which offers advice on lasers and laser applications.

When lasers in the ultraviolet range became commercially available in the early 1980s , he and Samuel E. Blum and James J. Wynne discovered in 1981 that a UV excimer laser can be used to precisely etch away tissue without causing thermal damage to the surrounding tissue. He called the process ablative photodecomposition ( Ablative Photodecomposition , APD). From 1983 he worked with the ophthalmologist Stephen Trokel from Columbia Presbyterian Medical Center to use ADP to operate on the cornea , which led to LASIK . After the collaboration ended, Trokel applied for a patent on the joint discovery without Srinivasan's knowledge, which was later declared invalid. Srinivasan holds a total of 21 US patents.

Srinivasan has received many awards for his work. In 1997 he received the ACS Award for Creative Invention , the Max Delbruck Prize in 1998 and the RW Wood Prize in 2004 (with Wynne, Blum). In 2002 he was inducted into the National Inventors' Hall of Fame (as the first scientist of Indian origin) . He and his working group were awarded the National Medal of Technology for 2011. In 2013 he received the Russ Prize of the National Academy of Engineering .
