Tim Hudson resigned Tuesday night as chancellor of Arkansas State University, a position he had held for four years.

LITTLE ROCK — Tim Hudson resigned as Arkansas State University chancellor Tuesday, effective immediately, university officials said Wednesday.

Hudson, who had been ASU chancellor since 2012, met Tuesday with ASU System President Charles Welch and submitted his resignation via email that night, ASU System spokesman Jeff Hankins said. Hudson resigned as chancellor and as a business professor at the university.

“Please accept this as my resignation from Arkansas State University,” Hudson said in the email. “I wish the institution and everyone associated with A-State all success in the future. Go Red Wolves!”

Welch said in a statement Wednesday he had accepted the resignation and named Lynita Cooksey, ASU’s provost and chancellor for academic affairs and research, as acting chancellor. He said he would develop plans for a long-term interim appointment in the coming days.

Welch did not explain why Hudson resigned. Hankins said Hudson left no forwarding information for media queries and referred a reporter to Hudson’s resignation email, which also contained no explanation.

Hudson’s resignation comes on the heels of findings by auditors that ASU’s study abroad programs are unorganized. The Jonesboro Sun reported last week that the university planned to remove the program’s director, Deidra Hudson, who is Tim Hudson’s wife.

Welch said in his statement, “I want to thank Dr. Tim Hudson for his service to Arkansas State University. A-State experienced many significant milestones during his tenure, including the most academically talented freshman classes in university history, record numbers of graduating students, record annual fundraising totals, creation of a public-private partnership with New York Institute of Technology to bring an osteopathic medical school to the A-State campus, completion of multiple major capital projects including the Humanities Building, and unprecedented institutional successes in intercollegiate athletics.”

Welch added that “Dr. Hudson, his wife Dr. Dee Dee Hudson, and their entire family welcomed thousands of university supporters into the Chancellor’s Residence to showcase the many talented members of the university community. I appreciate Tim, Dee Dee, and their family for their many contributions to A‑State, and I wish them well in their future endeavors.”

Cooksey, a 1979 graduate of ASU, joined the faculty in 1993. She taught in the Department of Biological Sciences for several years and was named associate vice chancellor for academic services in 2000. She became vice chancellor and provost in 2012.
