Toby Berger

from Wikipedia, the free encyclopedia

Toby Berger (born September 4, 1940 in New York City ) is an American information theorist .

Berger studied electrical engineering at Yale University with a bachelor's degree in 1962 and at Harvard University with a master's degree in 1964 and a doctorate in applied mathematics in 1966 with Donald Winston Tufts ( Nyquist's problem in data transmission theory ). From 1962 he conducted research at Raytheon , from 1966 to 1968 as a Senior Scientist. In 1968 he became an assistant professor and from 1977 professor of electrical engineering at Cornell University . From 2006 he was at the University of Virginia .

He deals, among other things, with the theory of data compression in the multimedia sector under in channels with losses.

He is the co-founder of SightSpeed, a company specializing in video conferencing, IP telephony and instant messaging technology . In addition to Raytheon, he also advised IBM and Schlumberger. From 1987 he was editor of the IEEE Transactions in Information Theory and was President of the IEEE Information Theory Group.

In 1982 he received the Frederick E. Terman Award, in 2011 the Richard W. Hamming Medal and in 2002 the Claude E. Shannon Award . He is a member of the National Academy of Engineering and the American Association for the Advancement of Science and a Fellow of the IEEE . In 1975/76 he was a Guggenheim Fellow and 1980/81 Fellow of the Japan Society for the Promotion of Science.

Richard Blahut is one of his PhD students .
