Dr. Haas received his PhD in Biochemistry from the Northwestern University School of Medicine in Chicago in 1979 and completed his post-doctoral training at the Institute for Cancer Research of the Fox Chase Cancer Center in Philadelphia in 1983. With Dr. Irwin Rose at Fox Chase and Drs. Avram Hershko and Aaron Ciechanover of the Technion Institute in Haifa Israel, Dr. Haas co-discovered the role of ubiquitin in targeted protein degradation and cell regulation, which was awarded the 2004 Nobel Prize in Chemistry. We was Professor of Biochemistry at the Medical College of Wisconsin in Milwaukee until 2004, when he joined the Louisiana State University School of Medicine as Roland Coulson Professor and Chair of Biochemistry and Molecular Biology and Member of the Stanley S. Scott Cancer Center. Dr. Haas is internationally recognized for his work on the mechanism for post-translational modification of proteins by ubiquitin and discovery of ISG15-dependent regulation in innate cellular defenses against viral and bacterial infection.
