Resume of Career

Prof. Guohua Hu joined the Department of Electronic Engineering at The Chinese University of Hong Kong (CUHK) as an Assistant Professor in June 2019. He received his PhD degree in Engineering from the University of Cambridge in 2018. His major research topics during PhD included high-speed printing of graphene electronics, CMOS integration of printed graphene for sensing, and printed 2d material based nonlinear optical devices and photodetectors. His PhD thesis title was Printable 2D Material Optoelectronics and Photonics. During 2017-2019, he was a Research Associate at the Cambridge Graphene Centre, working on printable graphene/metal oxide gas sensors through Newton Fund, InnovateUK. Prior to PhD, he received his BEng degree in Solid-State Electronics from University of Electronic Science and Technology of China in 2013. His current research interest at CUHK is solution-processing and functionalisation of low-dimensional nanomaterials for printed electronics, with particular focus on electronic skins, flexible and wearable electronics, bioelectronics, photonics, sensing and energy.

Prof. Hu has authored/co-authored 22 peer-reviewed journal papers, 1 research book and 1 patent, with a total citation of >1,400 and an h-index of 17 (Google Scholar; Sept., 2019).
