During this time, he co-discovered the role of ubiquitin in protein turnover with Irwin Rose, Avram Hershko, and Aaron Ciechanover, who shared the 2004 Nobel Prize in Chemistry for this work. Dr. Haas served as afaculty member of the Department of Biochemistry at the Medical College of Wisconsin from 1983 to 2004, before joining the LSU Health Sciences Center as Roland Coulson Professor and Head of the Department of Biochemistry & Molecular Biology. Dr. Haas has authored over 100 papers, reviews, and book chapters focused on cell regulation by ubiquitin and other Class 1 ubiquitin-like proteins, particularly ISG15. He has held visiting professorships at the University of Coimbra, Portugal, and the Institute of Biological Chemistry of the University of Urbino, Italy.
