Jim Cregg

Dr. Cregg earned his PhD in biology from Rice University in Houston, TX in 1978 and was a postdoctoral fellow at Scripps Clinic and Research Foundation in La Jolla, CA from 1978 to1980. Previous appointments have been with BRL/Life Technologies in Gaithersburg, MD (1980-1983), the Salk Institute Biotechnology Industrial Associates in San Diego, CA (1983-1989), and the Oregon Graduate Institute in Beaverton, OR (1989-1999). In 1988, Dr. Cregg also spent a year on sabbatical in the Netherlands at the State University in Groningen.

Dr. Cregg was one of the founding Professors at KGI and has continued his research on the development and use of yeast, Pichia pastoris, as a system for the production of recombinant proteins, for which he is internationally known. His work has majorly impacted the development of pharmaceutical proteins such as the chimeric monoclonal antibody, which works against rheumatoid arthritis and certain cancers, and human serum albumen, a component of an artificial blood plasma; he holds 14 patents in this area. Dr. Cregg has been invited to give keynote addresses at numerous meetings and serves as a reviewer or executive editor on five peer-reviewed journals in the biotechnology field.
