Jian Wang obtained his BEng degree in Energy, Power System, and Automation Engineering from Xi'an Jiaotong University (China) with a distinguished honour (top 0.2%) in 2013. After that, he took one year of postgraduate study at the same university, majoring in solid mechanics. He worked as a visiting pre-doctor fellow at Northwestern University (USA) in 2017 and received his PhD degree majoring in mechanical engineering with a research excellence award (top 2%) from the Hong Kong University of Science and Technology in 2018. Before joining the School of Energy and Environment at the City University of Hong Kong (CityU) in 2021, he worked as an SNU Science Fellow researcher at Seoul National University.

Wang currently leads the DEEP (Dynamic Electrochemical Energy Process) research group at CityU, focusing on advanced electrochemical energy technologies aimed at achieving sustainable development goals, such as fuel cells, water electrolysers, and batteries. He has pioneered the in-situ control of dynamic electrode behaviours, opening new pathways to enhance electrochemical cell performance. Additionally, he has developed multiscale in-situ characterisation tools that provide in-depth insights into intricate electrochemical energy processes. His innovative approach to the development of high-performance and cost-effective electrode materials for water electrolysers has resulted in prototypes exceeding current industry standards, thus dramatically augmenting energy efficiency.

Wang has published over 80 peer-reviewed journal papers, including 7 in the Nature series. He has been an honoured speaker at numerous prestigious institutions, such as the Chinese Academy of Sciences. His achievements have earned him the "NSFC Excellent Young Scientist Fund (Overseas)" and "Stanford's top 2% most highly cited scientist.".
