The school announced Thursday that it has suspended William L. Merrill and barred him from the campus in Mount Pleasant.
The Associated Press left phone and e-mail messages Thursday night for Merrill, a 58-year-old tenured faculty member in the College of Education and Human Services.
According to the university, its information technology employees found "inappropriate material" on Merrill's computer Monday, and it suspended him that day.
Isabella County prosecutors have charged him with four counts of possession of child pornography and with possession of a switchblade.
