Dr. James Claus joined the Department of Animal Sciences at the University of Wisconsin-Madison in the fall of 1999 as an Associate Professor in a teaching-research position specializing in muscle foods technology. Jim served as the Director of the Meat Science and Muscle Biology laboratory. Jim was promoted to a Full Professor in 2012. Jim was a faculty member (1989, tenured in 1995) in the Department of Food Science and Technology at Virginia Polytechnic Institute and State University (Virginia Tech). Jim received his Ph.D. (1989) and M.S. (1982) from Kansas State University.

Jim’s research primarily is the area of meat quality with emphasis in two distinct areas of muscle foods that include: 1) meat color chemistry and 2) improvement in lean meat tenderness through modulation of prerigor biochemistry and the development of postmortem tenderization technologies. Additional focus involves functionality of non-meat ingredients on improving processed meat quality as well as the development of low-sodium, low-fat products. Recent efforts have also focused on eliminating salmonella located in lymph nodes within meat carcasses. Jim has published 76 refereed journals, two refereed conference proceedings, eight invited papers, and three book chapters (shockwave tenderization, muscle foods).

Jim worked in the meat industry after receiving his M.S. degree. Jim worked as a production supervisor (1982) Patrick Cudahy. While employed by Superior Brand Meats Incorporated, he was a food technologist (1983) at Sugardale Foods, and a quality control manager (1984) at Carriage Hill Foods. While pursuing his undergraduate degree at the University of Connecticut, he worked in the meat lab and managed the retail meat store.
