Gerald L. Hazelbauer, Ph.D. is Chair of the Department of Biochemistry at the University of Missouri-Columbia. The department is affiliated with both the School of Medicine and the College of Agriculture, Foods and Natural Resources. Dr. Hazelbauer received his Ph.D. in 1971 for work done with Julius Adler at University of Wisconsin-Madison and did postdoctoral work with Jean-Pierre Changeux at the Pasteur Institute. He then went to the Institute of Molecular Biology at the University of Uppsala in Sweden as a Sloan Fellow in Neurobiology and was later appointed Assistant Professor. He moved to Washington State University in 1981 and became Chair of the Department of Biochemistry and Biophysics in 1994. In 2000, he moved to his current position at the University of Missouri-Columbia.
Dr. Hazelbauer is a biochemist and molecular biologist who has studied transmembrane receptors and sensory transduction in bacterial chemotaxis since the field began in the mid-1960’s. He has made seminal and sustained contributions to the understanding of transmembrane signaling, the mechanism of sensory adaptation mediated by covalent modification of receptors and higher order interactions among receptors in supramolecular clusters. His work has helped make chemotaxis in Escherichia coli a paradigm for molecular descriptions of complex biological systems and two-component signaling. He identified the first chemoreceptor mutants and first molecular component in chemotaxis. This was the earliest identification of defined protein for a chemical receptor and showed receptors could be discovered by combining genetics and biochemistry.
His work has been supported by the Swedish Natural Sciences Research Council, the National Science Foundation, the McKnight Foundation, the American Cancer Society and continuously for over 30 years by the National Institutes of Health. He has been honored with an Alfred P. Sloan Research Fellowship, a McKnight Neuroscience Development Award and an American Cancer Society Faculty Research Award. He is a Fellow of the American Academy of Microbiology and the American Association for the Advancement of Science. He currently serves the Protein Society as Secretary/Treasurer, its representative to the FASEB Board, and member of the FASEB Finance Committee.
