Si Wu is a full professor at the University of Science and Technology of China (USTC). He studied polymer science at USTC and obtained bachelor’s degree in 2005. He was supported by the joint doctoral promotion programme working at USTC and the Max Planck Institute for Polymer Research (MPIP). After obtained PhD in 2010, he worked as a postdoctoral fellow at MPIP and was promoted to a group leader in 2012. He headed a research group at MPIP from 2012 to 2018. In 2018, he joined USTC as a full professor. His group synthesize new photoresponsive polymers, characterize them, explore their potential applications in photolithography, nanoimprint lithography, information storage, healable materials, reprocessable materials, recyclable materials, biomedicine, and light-guided self-assembly. The aim of his research is to better understand the relationship between structural changes, dynamics, and performance of photoresponsive polymers. Si Wu's group solve fundamental problems in photoresponsive polymers with the perspective of future applications.
