In Jan 2011, Prof. Haghighat joined the Nuclear Engineering Program in the Mechanical Engineering Department at Virginia Tech (VT).  He is the director of the Nuclear Science and Engineering Lab (NSEL) at the Virginia Tech Research Center (VTRC) at Arlington. Prior to that, Prof. Haghighat was a Florida Power & Light Endowed Term Professor at the Nuclear & Radiological Engineering (NRE) Department, University of Florida. Between July 2001 and Sept 2009, he served as Chair of the NRE Department, and between Oct 2008 and June 2010, he served at the Director of the University of Florida Training Reactor (UFTR). Prior to 2001, Prof. Haghighat taught at the Pennsylvania State University for 15 years.

Prof. Haghighat is a fellow of the American Nuclear Society (ANS). He is director of the Virginia Tech Transport Theory Group (VT3G). Over the past 27 years, Prof. Haghighat has been involved in the development of new particle transport computational methodologies and large computer codes for modeling and simulation of nuclear systems including reactors, nuclear security and safeguards systems, and medical devices. His work is recognized internationally. He has published over 230 papers, received several best paper awards, and presented numerous invited workshops, seminars, and papers nationally and internationally. He received the 2011 Radiation Protection Shielding Division’s Professional Excellence Award, and recognition award from the Office of Global Threat Reduction for his leadership and contributions to design and analysis for the University of Florida Training Rector HEU to LEU fuel conversion in 2006.

Prof. Haghighat is an active member of the American Nuclear Society, and has served at various leadership positions. He has served as Chair of the Reactor Physics Division (2012-13) and the Mathematics and Computation Division (2005-06), was co-founder of the Computational Medical Physics Working Group, and served as Chair of NEDHO (Nuclear Engineering Department Heads Organization) (2006-07).

Prof. Haghighat contributed to the formation of the SUNRISE (Southeast Universities Nuclear Reactors Institute for Science and Education) not-for-profit organization, and he was Chairman of the Board of SUNRISE (2010-2014), and currently is leading the LPCF (Low-Power Critical Facility) project. Prof. Haghighat represents VT on the board of the recently established Virginia Nuclear Energy Consortium (VNEC) Authority.
