Charles R. Johnson

Geoffrey S.M. Hedrick Senior Professor Emeritus
Electrical and Computer Engineering


C. Richard Johnson, Jr. was born in Macon, GA in 1950. He received a PhD in Electrical Engineering from Stanford University, along with the first PhD minor in Art History granted by Stanford, in 1977. After 4 years on the faculty at Virginia Tech, he joined the Cornell University faculty in 1981, where he is the Geoffrey S. M. Hedrick Senior Professor of Engineering and a Stephen H. Weiss Presidential Fellow.

At the start of 2007, following 30 years of research on adaptive feedback systems theory and blind equalization in communication receivers, Professor Johnson accepted a five-year appointment as an Adjunct Research Fellow of the Van Gogh Museum (Amsterdam, the Netherlands) to facilitate the interaction of art historians and conservation specialists with algorithm-building signal processors. In 2012, Professor Johnson was appointed a Scientific Researcher of the Rijksmuseum.

Professor Johnson retired in 2021 and was awarded emeritus status as the Geoffrey S. M. Hedrick Senior Professor Emeritus in ECE.
