Guskiewicz is the senior associate dean for natural sciences and an exercise and sport science professor but will step down and assume his new position on Jan. 1, 2016.
Current dean Karen Gil announced her resignation in November 2014 after six years in the position.
A search committee was created to find Gil’s replacement.
“I always thought I would serve five years, so serving this extra year has been fun,” Gil said. “I’ve really enjoyed working with our new chancellor and our new provost, and I’m just eager to return to my research and teaching.”
Gil, former chairperson of the Department of Psychology, said she would return to teaching at the University.
A month until Gil’s planned resignation in May 2015, fewer than 100 people had applied to fill her position.
The search remained incomplete before classes started in August, and Gil agreed to stay on as interim dean of the College of Arts and Sciences until January 2016.
Executive Vice Provost Ron Strauss led the search for the new dean as chairperson of the search committee.
