| Biography | Dr. Bean has served on the faculty since January 1997. From 1976 to 1996 he was on the staff of the Physics Research Division of Bell Laboratories, Murray Hill, New Jersey. At Bell Labs he was both a Distinguished Member of Technical Staff and Head of the Materials Science Research Department. He has published over 250 technical articles including invited papers in Science, Physics Today, Parity and the Proceedings of the IEEE. He has edited and co-authored two books, presented over 100 invited conference presentations, and received 14 US patents. He has served on organizing committees for the Silicon MBE Symposia, the International MBE Meeting, the Device Research Conference, the Electronic Materials Conference, the International Solid State Devices and Materials Conference, and several Materials Research Society Symposia. He was elected to the Executive Committee of the EMPD Division of the American Vacuum Society and serves on the Editorial Board of Applied Surface Science. He is a Fellow of the IEEE and a member of the Materials Research Society and the American Vacuum Society. Bean received a B.S. from the California Institute of Technology in 1972, followed by M.S. and Ph.D. degrees from Stanford University in 1974 and 1976. All degrees were in Applied Physics. |
