Steven Biegalski is the Chair of Nuclear and Radiological Engineering and Medical Physics Program at Georgia Institute of Technology. He has three degrees in nuclear engineering from University of Maryland, University of Florida, and University of Illinois, respectively. Early in his career Dr. Biegalski was the Director of Radionuclide Operations at the Center for Monitoring Research.  n this position Dr. Biegalski led international efforts to develop and implement radionuclide effluent monitoring technologies. This work supported both US national capabilities and international treaties. Dr. Biegalski was a faculty member at The University of Texas at Austin for 15 years and held the position of Reactor Director for The University of Texas at Austin TRIGA reactor for over a decade. He has advised 25 Ph.D. students to graduation and holds Professional Engineering licenses in the states of Texas and Virginia.


Dr. Biegalski's current research focus is on nuclear analytical methods, research isotope production, nuclear forensics, and nuclear non-proliferation.
