Forensic science is the application of science to the legal field, including criminal and civil laws, during criminal investigation. Forensic scientists -- also called criminalists -- perform chemical and physical research on evidence submitted by law enforcement agencies, including handwriting analysis to confirm the validity of a signature on a will, or examining a firearm, and the growth of technology has expanded the field. These professionals also provide testimony in courts of law.

Humanitarian and human rights workers also have a place in the field and are recognized by the Academy of Forensic Sciences.
