Turner, who also will be the defensive run-game coordinator, was named to the position Tuesday.
Turner has coached defensive linemen in the Southeastern Conference for 20 years: Texas A&M, Kentucky, Alabama, Vanderbilt and Florida, where he’s been the last three seasons. It’s also a reunion for Collins and Turner, who worked together at Mississippi State in 2013-14.
Turner replaces Marco Coleman, who left Georgia Tech to coach Michigan State’s defensive line.
Collins has rebuilt his staff after firing three assistants, including offensive coordinator Dave Patenaude, following a 3-9 season that ended with six consecutive losses. Collins also fired co-defensive coordinator and safeties coach Nathan Burton and cornerbacks coach Jeff Popovich.
Turner’s 36-year career also includes stints as a defensive assistant in the Atlantic Coast Conference at Virginia and North Carolina State.
