I have 9 years of experience in the field of fire protection engineering, with specific knowledge of fire origin and cause investigation, forensic toxicology and fire dynamics. I have published on such topics as electrically initiated fires, the assessment of ignitable liquid weathering in the determination of intentionally set fires, and the use of forensic toxicology in fire cause and origin investigation. I have testified on fire cause and origin investigation, product liability, and fire department operations and firefighter safety.
