Dean, who was named interim head coach following Ron Maestri's retirement at the end of the 2015 season, has spent the previous two seasons as an assistant coach for the program.
The former LSU standout and 2009 College World Series champion helped bring the Privateers double-figure win totals in each of his two years as the squad's hitting coach.
During his playing career, Dean quickly rose as one of LSU's premier hitters and was named MVP of the 2008 Southeastern Conference baseball tournament as well as garnering All-American honors multiple years.
Following his tenure in Baton Rouge, Dean was drafted in the eighth round of the Major League Baseball Amateur Draft in the summer of 2010 by the Los Angeles Dodgers where he spent two years in the minor league system.
After his two years of pro ball, the Crestview, Florida native spent one season as a volunteer assistant coach at his alma mater where he earned his degree in sports administration before joining the Privateer coaching staff in 2014.
A press conference will be held Tuesday afternoon on campus introducing Dean as head coach.
