He is a member of the UW-Madison Mechanical Engineering Board of Visitors, and is a UW-Extension instructor of laboratory mechanical design.
Nelson came to Madison in 1975 from Peoria, Illinois, where he received a BS in mechanical engineering from Bradley University. He earned his MS in mechanical engineering from UW-Madison a year later. When he’s not working on a design project, Nelson spends time with his two golden retrievers and buys, repairs and restores old Chevrolet pickup trucks.
