Cox actively competed in the areas of gymnastics, track and field, and taekwondo while in school. She is also proficient in boxing, muay Thai kickboxing, and fencing, and has had training in stage combat, period weaponry, and firearms. During high school, she had aspirations of becoming an Olympic gymnast, but instead chose to focus on drama and theater.
She has over 38 movie and television appearances to her credit. Her best-known movie credits include the 1999 Canadian movie Better Than Chocolate, and the movieThe Chronicles of Riddick. She received a Gemini Award nomination for her performance as Angela Ramírez in F/X: The Series. Cox was an original member of the UPN sitcom Girlfriends, cast as Lynn, for the pilot episode.
Cox's first role as a main character in a television series was that of Vicki Nelson in Blood Ties, a supernatural detective series based on the novels by Tanya Huff. Ironically, Tanya Huff later shared: "Back when Christina Cox was doing F/X: The Series, I used to point at the screen and announce, 'When she's a little older, she'd be brilliant as Vicki!"
She starred as astronaut-biologist Jen Crane in ABC's 2009 summer show Defying Gravity. Cox also appeared in an episode of Showtime's series Dexter, as police officer Zoey Kruger. She recently joined the cast of the 2011 ABC summer drama Combat Hospital (aka The Hot Zone), alongside Elias Koteas and Deborah Kara Unger.
Cox currently resides in Los Angeles, California with her husband Grant Mattos, who is a former NFL wide receiver for the San Diego Chargers. He appeared in the 2011 season of the CBS series Survivor.
