is the John D. Tickle Associate Professor in the Nuclear Engineering Department at the University of Tennessee, Knoxville. He is an experimental nuclear physicist with over 30 y of experience in conducting experiments at accelerators around the world. His expertise is in the field of measuring secondary neutron production cross sections and yields of interest in the field of radiation protection. His current areas of research are in the field of secondary particle production from heavy ion interactions relevant to space radiation protection, radioisotope production for medical, security, and power applications, and nuclear thermal propulsion systems. He teaches undergraduate and graduate courses in radiation protection, health physics, space radiation, isotope production, and radioisotope power systems.

Dr. Heilbronn has published over 130 articles in peer-reviewed journals. He currently leads several federally funded research projects and mentors several graduate and undergraduate students. He is a member of the American Physical Society, the American Nuclear Society, the American Society for Engineering Education, the Institute of Electrical and Electronics Engineers, and the Health Physics Society. Dr. Heilbronn received a BS in physics from the University of Montana, an MS in physics from the University of Illinois, and a PhD in physics from Michigan State University. Before coming to the University of Tennessee in 2008, he worked at Lawrence Berkeley National Laboratory.
