Randy Dunn has been serving as the campus' overseer since interim chancellor Paul Sarvela died of cancer in November.
Dunn has appointed a search committee co-chaired by Carl Flowers, the director of the university's Rehabilitation Institute, and Meera Komarraju, chairwoman of and professor in the psychology department.
Dunn says the 18-member committee will meet this week.
Sarvela worked at SIU for 28 years, including as a faculty member, dean and associate vice president. He was named interim chancellor last July after former Chancellor Rita Cheng left to become president of Northern Arizona University.
