Explosives Pyrotechnic Expert Witness

Provides Opinion & Testimony In:

Explosives, Pyrotechnics, Propellants, Energetic Materials, Chemicals, Stability, Chemical safety, Thermal Stability, Explosions


Professor of Chemistry at the University of Rhode Island (URI), the former co-Director of the Department of Homeland Security (DHS) Center of Excellence (CoE) in Explosive Detection, Mitigation, and Response, and co-Director of the Forensic Science Partnership of URI. Expert earned a Ph.D. from the University of British Columbia (Chemistry) and joined the faculty of New Mexico Institute of Mining & Technology (NMT) where she founded a Ph.D. program in explosives and created a Thermal Hazards Research group. In 1995 she and her research group moved to URI, where her lab specializes in the study of energetic materials—explosives, propellants, pyrotechnics.

Expert has organized numerous symposia and short courses for government and industrial laboratories on topics ranging from hazards analysis to bomb threats: Sandia and Los Alamos National Labs; NAVSEA, Indian Head & Stumpneck; US Army R&D (WES) & Picatinny Arsenal; Edwards & Eglin Air Force Bases; CIA; Defense Nuclear Safety Board; DHS & Transportation Security Administration; Raytheon; Lockheed; AS&E; Implant Sciences. Expert is the past chair of the Gordon Research Conference (GRC) on Energetic Materials; co-founder of Life Cycles of Energetic Materials and the GRC on Illicit Substance Detection. She is an elected fellow of the North American Thermal Analysis Society and a reviewer for the FBI, NSF, Department of Justice, and National Academy of Sciences (NAS) National Research Council (NRC). Expert has served on seven NRC panels/committees In 2015 Expert was given a 2-year appointment to the NIST Organization of Scientific Area Committees on Fire Debris and Explosives.  She will begin a 3-year term on the DoD strategic Environmental R&D Program Scientific Advisory Board. She is on the editorial boards of Forensic Chemistry and Central European Journal of Energetic Materials.

Expert has authored over a hundred papers on energetic materials (explosives, propellants, pyrotechnics). She has worked on law enforcement issues [with the FBI simulating the World Trade Center bombing (1993), with FEL examining large fertilizer bombs, and with ATF studying the behavior of pipe bombs]; however, her main research interest is hazard analysis. Studies include kinetics, analysis and prediction of stability, safety issues, synthesis of energetics, and analytical protocols. Her study of ammonium nitrate stability and terrorist usage has led to an invitation to testify before a subcommittee of the House Homeland Security Committee (Dec. 2005) and her work on explosive detection before the House Science & Technology Committee (April 2008). Oxley has studied most classes of energetic materials including improvised explosives such as, hydrogen peroxide, TATP, and HMTD. The later has resulted in safe-scent canine training aids, licensing in progress. Work has been performed for a variety of companies (BASF, Battelle, Dow Chemical, DuPont, Exxon, Honeywell, Raytheon) and government agencies (U.S. Army, Navy, Air Force, FAA, TSA, DARPA, and Sandia & Los Alamos National Labs). Oxley’s URI laboratory is equipped with state-of-the-art analytical instruments: calorimeters, chromatographs, and mass spectrometers.  Her labs also include TSA explosive detection equipment: IMS, conventional X-ray & CT; and she maintains a 30-TNT eq licensed range equipped with various high-speed cameras. She holds DOE & DoD secret clearances.
