I have 32 years of experience and specialize in the field of demonstrative evidence with specific knowledge in the areas of fire and accident scene documentation and reconstruction, 3D computer modeling and exhibit design, and production. I have published on such topics as scale models for use in court, demonstrative evidence supporting the litigation process and getting exhibits admitted as demonstrative evidence. I have testified 6 times on topics such as fair and accurate representation of subject depicted by exhibits, process used in creation of exhibits and getting exhibits admitted as demonstrative evidence at trial.
