Prof. Ting Xu received Ph.D in Polymer Science and Engineering at the University of Massachusetts, Amherst in 2004 and postdoc training at the University of Pennsylvania and NIST. She jointed University of California, Berkeley in 2007 in the Department of Material Sciences and Engineering and Department of Chemistry. Her research focuses on rational design of polymer-based hybrid materials for life science, environment and energy applications. She is a fellow of American Physical Society, American Chemical Society and serves on the Board of Directors of Materials Research Society. Nature regularly programs complex processes to achieve system-wide, long-term sustainability. Successfully interfacing enzymes and biomachineries with polymers affords on-demand modification and/or programmable plastic degradation during manufacture, utilization, and disposal. The imminent question is how to program the life-cycle of plastics by molecularly regulating biocatlaysis inside of polymers without compromising host properties or creating 2nd contamination. With this project Ting Xu and her team found a solution on how to program biodegradable plastic.
