Youngstown State University has voided the contract of its current president, allowing the man to become president of Southern Illinois University.  In a statement late Wednesday, Youngstown State announced Randy Dunn will vacate the university’s presidency on March 21st and will have 30 days to move out of the presidential residence.  Dunn’s contract with the Ohio university required him to give the school 180 days of notice that he is leaving.  Youngstown State’s Board Chairman says the agreement allows the university to concentrate on the future.  SIU’s board last month hired Dunn to succeed Glenn Poshard, who has said he plans to step down from SIU’s helm at the end of June.
