Dr Qingfeng Zhai is currently a Lecturer and ARC DECRA Fellow at the Australia Carbon Materials Centre (A-CMC), School of Chemical Engineering, University of New South Wales (UNSW Sydney). Dr Zhai received his PhD degree from Changchun Institute of Applied Chemistry (CIAC), Chinese Academy of Sciences (Changchun, China) in 2018, with his research focusing on the fabrication of various high-efficiency electrochemical sensors. From 2018 to 2020, Dr Zhai worked as a Postdoctoral Research Associate at Monash University, developing highly flexible energy storage and sensing devices for wearable applications. After that, Dr Zhai moved to UNSW Sydney, working under the supervision of Prof. Liming Dai as a senior Postdoctoral Research fellow. Currently, his research focuses on carbon-based materials for electrocatalysis and sensing applications. This includes using the advanced in-situ characterization technique, such as electrochemical scanning tunneling microscope (EC-STM), for the catalytic mechanism study from the atomic scale, as well as screening or developing highly efficient carbon catalysts for diverse applications, including energy conversion and green chemistry.
