Associate Professor Yun-Xiang Xu is affiliated with the College of Polymer Science and Engineering at Sichuan University. Dr. Yun-Xiang Xu earned his Bachelor's degree from Shanghai Jiao Tong University and his Doctorate from the Shanghai Institute of Organic Chemistry. He subsequently pursued postdoctoral research at the University of Illinois at Urbana-Champaign and Washington University. He commenced his teaching and research career at Sichuan University in 2014. He has published over 80 articles in journals such as Advanced Materials, Angewandte Chemie International Edition, and ACS Applied Materials & Interfaces, garnering over 3000 citations with an H-index of 30. He holds 7 authorized patents.

His research focuses on polymeric materials, particularly synthetic rubber. He aims to achieve high performance, high value, and recyclability of rubber products through approaches such as catalyst system design, multi-scale structural control, integrated design of synthesis and processing technologies. In recent years, his research has focused on two main areas: 1) the synthetic chemistry of natural rubber and 2) the development and application of novel reversible bonds in polymeric materials.
