Rob Hayes

Associate Professor of Nuclear Engineering, Joint Faculty Appointment with SRNL

Dr. Hayes’ thrust areas span nuclear nonproliferation including nuclear assay and retrospective dosimetry. He also finds health physics, nuclear crtiticality safety, burnup, shielding, nuclear waste disposal and novel detection methods of interest, particularly when they relate back to nonproliferation. Dr. Hayes is a Certified Health Physicist and a licensed Professional Engineer (nuclear) with industry and field experience in radiological emergency response, nuclear waste management, nuclear safety, radiation dosimetry, nuclear criticality safety, air monitoring, ALARA and shielding design.

Research Description

Dr. Hayes' research interests include nuclear nonproliferation, radiological emergency response and nuclear waste disposal technologies which are advanced using novel hybrid approaches including radiation detection, air monitoring, luminescence and magnetic resonance coupled with Monte Carlo radiation transport modeling. His research includes luminescence and magnetic resonance techniques on free radicals created from exposure to ionizing radiation in conjunction with air monitoring technologies related to consequence assessment and emergency response. Tying all these together are novel detection methodologies which include HPGe applications for field assay coupled with low resolution detector platforms. Modeling these effects with Monte Carlo radiation transport codes to interpolate and extrapolate from measured values then allows useful predictions tied back to measurement. His background includes many years of industrial experience at a nuclear waste repository and on the federal radiological emergency response teams.
