Professor Xiangjun Gong is a doctoral supervisor. She graduated with a bachelor’s degree from University of Science and Technology of China in 2005 and a doctoral degree from the Chinese University of Hong Kong in 2011. From 2011 to 2013, worked as a postdoctoral researcher at the Chinese University of Hong Kong. Joined the School of Materials Science and Engineering at South China University of Technology as an associate professor in 2014 and has been a professor since 2017. Her research interest is to design high-precision real-time characterization tools based on optics and electromagnetics to study the dynamic behavior and physicochemical phenomena of particles, microorganisms, organisms, and environmental molecules near material interfaces. Specifically, it includes: (1) the development of high-precision optical characterization technology for 3D real-time tracking; (2) The interaction, adhesion mechanism, and movement strategy between particles and microorganisms at the near interface; (3) The dynamic behavior of biological molecules and environmental pollution molecules at various interfaces; (4) Microbial and cell screening, identification, and control technologies.
