I have Bachelor degrees in biology and chemistry, and a Masters degree in chemistry, while my knowledge of American history stems more from a life-long passion. I have been employed for over 30 years, in various laboratories, primarily as a Forensic Scientist in a crime laboratory. In addition to my teaching experience as a teaching assistant in graduate school, I have taught many police officers and prosecutors. Particularly in the sciences, I often relate my lessons to my work in the crime lab.
