"We are very happy to welcome Coach Wolthausen to our staff," Hope said. "His background and expertise will be a real asset to the Boilermaker program. He has coached at the highest levels of both professional and collegiate football and has honed his craft along the way."
During Wolthausen's coaching career, he has helped lead 17 teams to postseason bowl games, including four Rose Bowls.
Prior to spending the 2007 season with the Atlanta Falcons, he spent four seasons at Louisville. Starting with the Cardinals as the linebacker coach, he moved on to defensive line and eventually became co-defensive coordinator in 2006.
In 2005, Wolthausen mentored defensive end Elvis Dumervil to consensus All-America honors. Dumervil, who broke the NCAA record with six sacks against Kentucky, was named the 2005 Big East Player of the Year, while also winning the Bronko Nagurski and Ted Hendricks awards. Dumervil was selected in the fourth round by the Denver Broncos in the 2006 NFL Draft.
Wolthausen began his coaching career in 1980 as student assistant at Cal State Northridge before returning to his alma mater, Humbolt State, as a part-time defensive assistant from 1980 to 1982.
He joined the University of Arizona as a graduate assistant for a pair of seasons (1983-84) before becoming full-time with the Wildcats as the outside linebackers coach in 1985 and defensive line coach in 1986.
In 1987, Wolthausen followed head coach Larry Smith from Tucson to the University of Southern California where he helped guide the Trojans to three Rose Bowl appearances in six seasons (1987-92).
After spending two winning seasons as the defensive line coach at Oklahoma in 1993 and 1994, Wolthausen moved on to Arizona State where he would work with same defensive unit. With Wolthausen on staff, the 1996 Sun Devils came up just shy of winning at least a share of the school's first national title after falling to Ohio State 20-17 in the final seconds of the 1997 Rose Bowl. ASU finished the year ranked fourth nationally with an 11-1 record.
Wolthausen joins the Boilermakers from the Las Vegas Locomotives in the United Football League where he served as the defensive line coach. The Locomotives won UFL titles in 2009 and 2010 and lost in the championship game in 2011.
