Forensic chemistry and causation analysis define his expert witness practice, supported by more than 25 years of experience in forensic investigation, consultations, depositions, and courtroom testimony. He has a background in chemistry, geology, and mechanics, with expertise in laboratory characterization and identification of unknown materials, deposits, residues, and potential sources. His work includes chemical analysis of fire debris, fluid analysis involving oils, gasoline, accelerants, and combustible residues, consumer product analysis, and forensic investigation of failures involving industrial processes, materials, and construction systems.

His forensic investigations include determining the cause of failures involving adhesives, paints, coatings, concretes, plastics, metals and corrosion, wood, plaster, glass textiles, fluids, oils, and other materials. He conducts material characterizations, comparisons, simulation testing, and identification of unknowns, and he designs and executes laboratory test plans to simulate or recreate explosions, fires, chemical reactions, and physical damage. His forensic investigation experience also includes evidence collection and transfer, distribution mapping, photography, acquisition of technical data and witness statements, microscopy, micro-measurements, specimen preparation, micro-chemistry techniques, and characterization and identification of particulate matter, fibers, and physical tool marks.

He holds a Bachelor of Science in geology and chemistry and an Associate of Arts in geology. He is a licensed unarmed private investigator in Washington and has specialized training in investigative locksmithing, including forensic analysis of keys, transponders, and locks. His technical experience includes more than 25 years using Fourier Transform Infrared Spectroscopy for qualitative analysis of organic and inorganic materials, more than 25 years using gas chromatography for quantitative and qualitative analyses of fuels, oils, solvents, and combustible residues in fire debris, more than 25 years using wet chemical analysis, 25 years using microscopy, and more than 5 years conducting petrographical examinations of natural stone and hardened concrete. He is a member of the International Association of Investigative Locksmiths, Inc.
