I have 22 years of experience, and specialize in the field of forensic document examination with specific knowledge in the areas of handwriting comparison, indented writing examinations and the nondestructive examination of inks. I have published on such topics as photocopier examinations, the sequencing of entries on documents and the examination of indented handwriting entries. I have testified 99 times on topics such as the authenticity of signatures and handwritten entries, the comparison of inks used in handwriting entries and the detection and decipherment of indented writing images.
