WANG Qing

Dr. Qing Wang is a Professor at the Department of Materials Science and Engineering, National University of Singapore. He obtained PhD in Physics at the Institute of Physics, Chinese Academy of Sciences in 2002. Before he moved to Singapore in 2008, he had worked as a postdoc research fellow at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, and National Renewable Energy Laboratory (NREL), USA, in the area of mesoscopic photoelectrochemical cells. Dr. Wang is a recipient of NUS Engineering Young Researcher Award (2014), NRF Investigatorship (2018), and NUS Dean’s Chair Associate Professor (2021).

Research Interests

My research focuses on charge transport in mesoscopic electrochemical systems, exploring their applications in advanced energy conversion and storage. Currently, my team is leading a novel approach cantered on redox targeting of energy materials for large-scale storage and other innovative uses, including on-demand hydrogen production, metal-air electrical power generation, high-throughput recycling of spent battery materials, and the synthesis of value-added chemicals, etc. We are conducting extensive translational studies in the lab to advance these technologies toward practical deployment.
