Chandrashekhar Janardan Joshi (born July 22, 1953, at Wai, Maharashtra, India) is an Indian–American experimental plasma physicist.
[2] Joshi was elected a member of the National Academy of Engineering in 2014 for contributions to development of laser- and beam-driven plasma accelerators.
He is currently Distinguished Professor of Electrical Engineering, the director of the Center for High Frequency Electronics and the head of the Neptune Laboratory for Advanced Accelerator Research at UCLA.
At UCLA, Joshi has built a strong research group that has done pioneering work in the areas of laser-plasma instabilities,[4] plasma-based light sources,[5] laser fusion[6] and basic plasma experiments.
[7] 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.
