Mae Jarvis is the Medical Examiner and field agent of the FBI's International Response Team, which appears in the spin-off Criminal Minds: Beyond Borders. She and the rest of her team appeared in the Season Ten episode of Criminal Minds, "Beyond Borders".
As a medical student, Jarvis decided to become a medical examiner after her first cadaver was a woman her age. The experience caused her to realize that she should dedicate herself to giving dead people closure and perhaps justice by examining their bodies. At some point, she was briefly engaged to a man but later called off the wedding due to her devotion to her job with the International Response Team. She served as the IRT's personal medical examiner to aid in investigating crimes involving dead bodies.
- Her sidearm is a 9mm Smith & Wesson M&P Shield.
