Krug received both his M.A. (1968) and Ph.D. (1971) degrees in Psychology from the University of Illinois, Urbana-Champaign. He is currently chairman and CEO of MetriTech, Inc., an educational testing company that works primarily with large-scale, state testing programs. He has published many articles, books, and tests. His articles and books all relate to issues in applied personality and educational measurement. Krug has been a member of Psychology's Alumni Advisory Board since its inception in 2008. He has worked with Advisory Board member Denise Dallmier Burger to arrange and conduct mock interviews for students in the Capstone Internship Seminar. These mock interviews provide students not only with a realistic introduction to interviews in the business world, but gives them feedback and suggestions so that the students can be successful as they embark on their career paths. Sam has been very generous with his support to allow these mock interviews to be held during lunches at the Champaign Country Club.
