Having 13 years of consulting experience, they serve as an expert witness in nuclear criticality safety, non-destructive assay, radioactive waste management, shielding analysis, particle transport analysis, safety and compliance reviews, audits, and reactor physics. Their background includes DOE, NRC, and USACE-regulated work involving decommissioning and remediation projects, nuclear facility evaluations, fissile material handling operations, process gas piping measurement, criticality safety controls, and radioactive waste characterization. They hold a Ph.D., M.S., and B.S. in Nuclear Engineering, along with certificate training in radiation technologies and accelerator school coursework.

Their nuclear criticality safety work includes evaluations, determinations, criticality accident alarm system omission bases, Monte Carlo calculations, MCNP validation, SCALE calculations, shielding design calculations, transmutation and decay calculations, and dose assessments. They have performed analyses involving medical isotope production facilities, hot cell operations, linear accelerator-driven production facilities, radioisotope production, reactor decommissioning, uranium oxide, uranium solutions, and High Flux Isotope Reactor target isotope production.

They have held senior technical responsibilities involving nuclear criticality safety, non-destructive assay, safety and compliance analysis, program development, management assessments, regulatory interface, inspection support, incident investigation participation, emergency response preparedness, and remediation planning. Their work has included technical approaches for waste disposal trenches, highly enriched uranium, plutonium residues, standpipes, bunkers, process building deactivation, demolition, and burial. They are a member of the American Nuclear Society and the ANSI/ANS-8.28 Working Group, and they hold an active DOE “L” Clearance.

Their non-destructive assay experience includes fissile material measurement methods, threshold count rate calibration, detector test planning, measurement programs, MCNP calibration analyses, portable gamma spectroscopy, and characterization of uranium hold-up in process gas piping. They have also supported development and implementation of systematic measurement approaches for process gas piping and nuclear criticality safety limits connected to field measurements.
