Dr. Alireza Nojeh
Professor
Department of Electrical and Computer Engineering
Alireza Nojeh works on electron emission phenomena and vacuum nanoelectronic devices including free-electron instruments and energy converters. Much of his work has revolved around optical excitation of carbon nanotubes leading to localized heating and the thermal emission of electrons and photons. He studied at Sharif University of Technology (BS, MS), the University of Paris XI-Orsay (DEA), and Stanford University (PhD). He has been at UBC since 2006, where he is a professor in ECE and an investigator at
