Dr Shiwei Wang PhD, SMIEEE

Dr Shiwei Wang is an Associate Professor in Centre for Electronics Frontiers (CEF), School of Electronics and Computer Science. He received his Bachelor degree in Electronic Engineering (Outstanding Honor) from Zhejiang University, China in 2010 and PhD degree in Microelectronics from University of Edinburgh, UK in 2014. Following his PhD research, he was with SIAT, Chinese Academy of Sciences, China as a Research Assistant Professor before moving to IMEC, Belgium where he worked as a Senior Researcher till December 2020. At IMEC he took technical lead in several projects to develop ultra-low-power integrated circuits for neural interfacing applications. His research at IMEC has led to innovative breakthroughs in high density neural probe. He is a senior member of IEEE and has over 20 publications including premier journals and conferences such as Science, JSSC, TBCAS, ISSCC, VLSI, IEDM, etc.

At CEF, he is extending his research to empower future AI with integrated CMOS-memristive circuits and systems.
