Zhenglong Xu is currently an assistant professor in the Department of Industrial and Systems Engineering at The Hong Kong Polytechnic University (PolyU). He received his BSc in materials science and engineering from Zhejiang University in 2012 and his PhD in mechanical and aerospace engineering from The Hong Kong University of Science and Technology (HKUST) in 2016. Before joining PolyU, he worked as a postdoctoral research fellow at HKUST, PolyU, and Seoul National University. Zhenglong's research focuses on the design, fabrication, and characterisation of advanced energy materials and devices, such as rechargeable batteries. He has also established multimodal in-situ characterisation technique — including electrochemical testing, in-situ Transmission Electron Microscopy, and operando synchrotron X-ray—to probe fundamental mechanisms in energy storage and conversion systems.
