After that show ended, she went on to graduate Summa cum Laude from UCLA with a degree in Mathematics, and even proved a new math theorem, the Chayes-McKellar-Winn Theorem. Since returning to acting, Danica became familiar again to audiences from her year-long turn as the sardonic, dry-witted Elsie Snuffin on The West Wing (1999) in its 4th season. Since then, Danica made guest appearances on shows such as NYPD Blue (1993), Jack & Bobby (2004), Eve (2003), NCIS (2003), and she played a strung-out heroin addict on Lifetime's Strong Medicine (2000). Danica got her feet wet as a filmmaker with her award-winning short film Speechless... (2001) (co-starring The Wonder Years (1988) pal Dan Lauria), which she wrote, directed, and produced. Danica made her debut lingerie spread in the July 2005 issue of Stuff Magazine, in which she appears on the cover. Her pictures can also be seen on its Web site. Talk about allure. Read less
