David A. Tirrell (born 1953) is an American chemist and the Ross McCollum-William H. Corcoran Professor and Professor of Chemistry and Chemical Engineering at the California Institute of Technology (Caltech). A pioneer in the areas of polymer synthesis and protein biosynthesis, his research has a wide range of applications, including coatings, adhesion, lubrication, bioengineering and biomedical intervention. As of 2012[update] he became Director of the Beckman Institute at Caltech, succeeding Barbara Wold.
Dr. Tirrell earned a B.S. in Chemistry at the Massachusetts Institute of Technology (MIT) in 1974. He received a Ph.D. in 1978 from the University of Massachusetts Amherst where his thesis advisor was Professor Otto Vogl. In 1978, he held a postdoctoral position at Kyoto University.
Dr. Tirrell was a faculty member in the Department of Chemistry at Carnegie-Mellon University from 1978-1984. He served as the Director of the Materials Research Laboratory at the University of Massachusetts Amherst from 1978-1998. He moved to Caltech in 1998 and served as chairman of the Division of Chemistry and Chemical Engineering at Caltech from 1999 until 2009. He edited the Journal of Polymer Science from 1988-1999.
Tirrell applies principles from biology and chemistry to polymer synthesis. Recognizing that most synthetic polymers are mixtures, rather than pure substances, he developed pioneering techniques for the creation of precisely-defined polymers of uniform structure. Tirrell and his co-workers have formed crystals, liquid crystals and gels with predetermined, programmable molecular architectures and accompanying properties. His work in macromolecular synthesis underlies the development of "smart" materials, which respond to external cues like temperature, pH, chemical reagents, or light.
