Buhrman, Robert A. - Cornell University - Applied and Engineering Physics

个人简介

Robert Buhrman received his B.E.S. degree in 1967 from Johns Hopkins University in Engineering Physics, with departmental and general honors. He completed his Ph.D. studies at Cornell University in Applied Physics where his thesis research was on the superconducting properties of Al nanoparticles. Buhrman joined the Cornell Faculty in 1973 and is currently the John Edson Sweet Professor of Engineering in the School of Applied and Engineering Physics. He served as Director of Applied and Engineering Physics from 1988 to 1998. Buhrman was part of the Cornell faculty team that won the national competition for the original National Science Foundation funding for what is now the Cornell Nanoscale Facility (CNF), which is now one of the two major nodes of the National Nanofabrication Infrastructure Network. He served as Chair of the CNF Executive Committee from 1985 to 2002. Buhrman was also the founding (2001-2007) Director of the Center for Nanoscale Systems in Information Technologies, which was a National Science Foundation and New York State supported multidisciplinary research center from 2001-2012. Since 2007 Buhrman has also served as Cornell's Senior Vice Provost for Research. Buhrman is an Elected Fellow of the American Academy of Arts and Sciences.
