Name  Chandrashekhar Joshi

Chandrashekhar "Chan" Janardan Joshi (1953, India – ), is an American experimental plasma physicist and a pioneer of the Plasma-based particle acceleration techniques. He received the Maxwell prize in plasma physics in 2006 for leadership in plasma-based acceleration techniques. Chandrashekhar J. Joshi is a Distinguished Professor of Electrical Engineering at UCLA. He is also the Director of Center for High Frequency Electronics and heads the Neptune Laboratory for Advanced Accelerator Research at UCLA.

Education

He received his B.Sc. (1974) in nuclear engineering from London University and Ph.D. (1978) in applied physics from Hull University, both in the U.K. Following a two-year stint as a research associate at the National Research Council of Canada, where he worked on laser-plasma interactions, he joined UCLA first as a researcher and since 1988 as a faculty member.

Research

At UCLA, Professor Joshi has built a strong research group that has done pioneering work in the areas of laser-plasma instabilities, plasma-based light sources, laser-fusion and basic plasma experiments. Joshi has made many fundamental contributions to the understanding of extremely nonlinear optical effects in plasmas. Most notable including his first experimental demonstration of four-wave mixing, stimulated raman forward instability, resonant self-focusing, frequency upshifting by ionization fronts and nonlinear coupling between electron-plasma waves. His group is best known, however, for developing the field of plasma based particle accelerators over the past three decades.

Awards and recognitions

Professor Joshi is a Fellow of the APS, IEEE and Institute of Physics (U.K). He is also the recipient of DPP's Excellence in Plasma Physics Award (1996) (awarded jointly with Christopher E. Clayton ) and USPAS prize for Achievement in Accelerator Physics and Technology (1997). He was the APS Centennial Speaker (1999) and a Distinguished Lecturer in Plasma Physics (2001). He was elected to the National Academy of Engineering in 2014.
