Brief Biosketch

Dr. Xu is currently an Assistant Professor in the Department of Industrial and Systems Engineering at The Hong Kong Polytechnic University. Dr. Xu received his BSc degree in Materials Science and Engineering from Zhejiang University (2012) and PhD degree in Mechanical and Aerospace Engineering from Hong Kong University of Science and Technology (2016). Before joining ISE at PolyU, he worked as Postdoc/Research Fellow at HKUST, PolyU and Seoul National University. His research interest mainly lies in the design, fabricate and characterization of advanced energy materials and devices, such as rechargeable batteries. He has also established multimodal in-situ characterizations, including electrochemical testing, in-situ TEM, operando synchrotron X-ray etc, to probe into the fundamentals in energy storage/conversion systems. His work has been published on top journals in the field including Nature CommunicationsAdvanced MaterialsEnergy Environmental ScienceProgress in Materials Science and Advanced Energy Materials.
