"I'm very excited to welcome Chris aboard," Bielema said. "He brings great knowledge and tremendous experience. I've known Chris for a long time and his familiarity not only with our staff but with our schemes will help in what I think will be a seamless transition for him and the rest of our coaches."
Ash has spent eight of the last 10 seasons at Iowa State, beginning as a defensive graduate assistant in 2000. He was promoted to secondary coach in 2002 and added the title of recruiting coordinator in 2006.
Following the 2006 season he moved on to become the secondary coach and recruiting coordinator at San Diego State. He stayed there for two seasons before returning to Iowa State in the same position.
"I'm very excited to have the opportunity to work at a wonderful university like Wisconsin and with a football program with such a great history of success," Ash said. "I am really looking forward to working for Coach Bielema and alongside Coach Doeren and Coach Partridge, two coaches I have worked with in the past and have great respect for."
Ash began his career as a volunteer assistant at Drake in 1996. The next season he served as a defensive graduate assistant for the Bulldogs. During those two seasons he was on the same staff as current UW assistants Dave Doeren and Charlie Partridge. When Doeren left Drake following the 1997 season, Ash took over his role as defensive coordinator for two seasons.
Ash has coached in six bowl games in his career, including the 2009 Insight Bowl when Iowa State defeated Minnesota. Last year's Cyclones' defense finished ninth in the country with 32 takeaways and tied for second in the nation in red zone efficiency. In 2005, Iowa State led the Big XII in interceptions (22) after finishing second in the conference the prior year (17).
Ash graduated from Drake with a bachelor's degree in secondary education in 1996. He received his master's degree in education from Iowa State in 2005. A native of Ottumwa, Iowa, Ash and his wife, Jessica, have two children, Tanner (8) and Jacey (6).
