Teaching Interests
Professor Biegalski’s teaching interests include undergraduate and graduate courses in nuclear engineering, radiation detection, and measurement, as well as applied nuclear physics. His teaching emphasizes foundational principles and practical applications in nuclear science and engineering. He is committed to involving students actively in learning processes and fostering critical thinking in topics related to nuclear instrumentation and radiation safety.
Research Interests
Professor Biegalski's research spans advanced nuclear reactor design and operations, nuclear analytical methods, and nuclear forensics, with a long-standing focus on applying rigorous measurement science to problems of national and international security. He has led and contributed to the design, licensing, and operation of advanced nuclear reactors. A central theme of his work is the development and application of nuclear analytical techniques including neutron activation analysis, prompt gamma activation analysis, neutron imaging, and high-resolution gamma spectroscopy to characterize nuclear materials, environmental samples, and post-detonation debris. He is internationally recognized for foundational contributions to radioxenon science, encompassing radioxenon production, β–γ coincidence detection, atmospheric transport, subsurface migration, and forensic signature interpretation in support of nuclear explosion monitoring and treaty verification. These sustained contributions to radioxenon research and nuclear monitoring were recognized by the award of the 2025 Hevesy Medal, reflecting the impact of this work on nuclear forensics, emergency response, and global nonproliferation efforts.
