Dr. Steven Biegalski earned his Ph.D. in nuclear engineering from the University of Illinois at Urbana-Champaign in May 1996. He joined the faculty of The University of Texas at Austin in 2002. Dr. Biegalski is currently the Director of the Nuclear Engineering Laboratory (NETL). He is licensed as a Professional Engineer in the states of Texas and Virginia. His research focuses on nuclear analytical methods, nuclear instrumentation, nuclear reactor design, and nuclear reactor operations. Dr. Biegalski’s research includes the development and utilization of instrumental neutron activation analysis (INAA), prompt gamma-ray activation analysis (PGAA), neutron depth profiling (NDP), and neutron radiography. He also conducts research that supports nuclear explosion monitoring and nuclear forensics. He has experience modeling environmental pathways with a special focus on atmospheric transport modeling. In the past he has worked to develop technology in support of nuclear treaties.
