Biographical Sketch
Michael Shapiro received a Ph.D in Radio Physics from the University of Gorky in 1990 in Russia. He has been with the Institute of Applied Physics, Nizhny Novgorod (former Gorky) from 1978 to 1994 where he worked on microwave transmission lines and mode converters. He immigrated to the US in 1995. Since then, he is with the MIT Plasma Science and Fusion Center. |
