Dr. Ed Bayer is a full professor in the Department of Biological Chemistry at the Weizmann Institute of Science, Rehovot, Israel. During his scientific career, he has pioneered two separate areas of research: the avidin-biotin technology and the field of cellulosomes. He is co-discoverer of the cellulosome concept in the early 1980s. In 1999, he organized and co-chaired the first Gordon Research Conference on "Cellulases and Cellulosomes," and he chaired the same conference in 2001. In 1994, he proposed the use of "designer cellulosomes" for biomass degradation, waste management, and as a general tool in the biological sciences. During his career, he has collaborated with groups in the United States, Canada, Holland, Belgium, Germany, Great Britain, France, Spain, Italy, Finland, Denmark, Guatemala, China, Japan, Australia, and the Republic of Georgia.
