Early life
Walker was born in Tullahoma, Tennessee, to James Joseph Walker, a physicist, and Louhannah (née Mann) who would become an attorney. She grew up in Santa Fe, New Mexico, where her father worked at the Los Alamos National Laboratory. Originally intending to become a scientist, she attended the University of California, Santa Cruz, where she earned a degree in biochemistry in 1983. While spending a semester at Richmond College of Arts in London, UK, she discovered an interest in performing. After graduation, she worked for a time sequencing DNA at a genetic engineering company, but then sold all her possessions, traveled to Australia, surfed, and worked a series of jobs before returning to Los Angeles. Although she planned to enter medical school, instead she became a model and obtained roles in commercials including as Clairol’s “Nice & Easy Girl.” Her acting career began when she was cast in the film Aloha Summer (1988), but her scene was cut from the final version.
