DESCRIPTION:Prof. Timothy Deming\, Chemistry and Biochemistry Department a
 nd Bioengineering Department - UCLA\nOur lab has developed synthetic metho
 ds that allow incorporation of unprecedented levels of functionality into 
 polypeptide materials. We report on the design and properties of stimuli r
 esponsive polypeptide motifs that are able to respond differently to diffe
 rent individual stimuli\, such as redox\, temperature\, or enzymes. These 
 materials allow multimodal switching of polypeptide properties to obtain d
 esirable features\, such as coupled responses to multiple external inputs.
  The reversible\, multi-responsive nature of these polypeptides makes them
  particularly attractive as components in molecular devices or nanoscale a
 ssemblies capable of sequential\, or triggered\, responses to different st
 imuli\, akin to switches capable of performing Boolean-like operations. We
  will describe how these motifs can be incorporated into self-assembled ma
 terials such as hydrogels.\nBio: Timothy J. Deming received a B.S. in Chem
 istry from the University of California\, Irvine in 1989\, and graduated w
 ith a Ph.D. in Chemistry from the University of California\, Berkeley\, in
  1993.  After a NIH postdoctoral fellowship at the University of Massachu
 setts\, Amherst with David Tirrell\, he joined the faculty in the Material
 s Department at the University of California\, Santa Barbara in 1995.  He
 re he held a joint appointment in the Materials and Chemistry Departments 
 where he was promoted to Associate Professor in 1999 and Full Professor in
  2003. His appointment is now as Professor of Bioengineering and Professor
  of Chemistry and Biochemistry at the University of California Los Angeles
 . He served as the Chairman of the Bioengineering Department at UCLA from 
 2006 to 2011. He is a leader in the fields of polypeptide synthesis\, self
 -assembly of block copolypeptides\, and biological activity of polypeptide
 s\, for which he has received awards from the National Science Foundation\
 , the Office of Naval Research\, The Arnold and Mabel Beckman Foundation\,
  the Alfred P. Sloan Foundation\, the Camille and Henry Dreyfus Foundation
 \, the Materials Research Society\, and the IUPAC Macromolecular Division.
  He is a Fellow of the American Institute of Medical and Biological Engine
 ering\, and recently received the Fulbright-Tocqueville Distinguished Chai
 r Award.
