Biography

Prof. Chang-Hasnain's CV

She received her B.S. from UC Davis, 1982, M.S. and Ph.D. from UC Berkeley, 1984, and 1987 respectively. She was a Member of Technical Staff at Bellcore from 1987 to 1992. From April 1992 to December 1995, she was Associate Professor of Electrical Engineering at Stanford University. January 1996 she joined EECS at UC Berkeley. She is the director of CONSRT, a center of 10 professors across 6 universities with a research focus of nanostructured semiconductor optoelectronic materials and devices.

Professor Chang-Hasnain has co-authored over 400 research papers in technical journals and conferences. She also holds more than 30 patents. Professor Chang-Hasnain was named a Presidential Faculty Fellow, a National Young Investigator, a Packard Fellow, a Sloan Research Fellow, and Outstanding Young Electrical Engineer of the Year by Eta Kappa Nu. She received the 1994 IEEE LEOS Distinguished Lecturer Award, the 2000 Curtis W. McGraw Research Award from the American Society of Engineering Education, the 2003 IEEE William Streifer Scientific Achievement Award, and the 2005 Gilbreth Lecturer Award from National Academy of Engineering. In 2009, she was named a Guggenheim Fellow. Professor Chang-Hasnain is a Fellow of the IEEE, OSA and IEE, and an Associate Editor for the IEEE Journal of Lightwave Technologies. She has been elected an Honorary Member of A.F. Ioffe Institute in 2005.
