In 1995, Clayton was named the Ralph Medinger Lenz Professor of Management Science, one of the first endowed professorships created in the college.

He served twice as president of the Southeast Institute of Management Science (now INFORMS), receiving its Distinguished Service Award.  

A well-recognized researcher, Clayton authored 40 research articles and one book. He was also a dedicated and very popular teacher.
