George Gilmer

Research Professor, Mechanical Engineering

George GilmerProf. Gilmer has an extensive background in government and industrial laboratories, together with teaching undergraduate physics early in his career. He started working full time at Mines in 2012, after 12 years at Lawrence Livermore National Laboratory. At Livermore Gilmer applied atomistic modeling of materials related to various aspects of the National Ignition Facility, which is being developed to produce fusion of hydrogen isotopes by inertial confinement.

Previously he was in Murray Hill, N. J., for 29 years, employed by Bell Telephone Laboratories, Lucent Technology, and Agere Systems, after various divestitures. Here most of his work involved atomistic modeling of crystal growth, and applications primarily to silicon processing involved in device fabrication.

Prior to this Gilmer was employed by Washington and Lee University, for eight years, and two years at Cornell University working as a research associate. His Ph. D. graduate study involved the theory of crystal growth, under Nicholas Cabrera at the University of Virginia. His B. S. was granted by Davidson College.
