Dr. Lou received the B.Eng. degree in Electronic Information Technology and Instrumentation from Zhejiang University (ZJU), China, in 2010 and M.Sc. degree in System-on-Chip Design from Royal Institute of Technology (KTH), Sweden, in 2012 and PhD degree in Electrical and Electronic Engineering from Nanyang Technological University (NTU), Singapore, in 2016. Then he joined VIRTUS, IC Design Centre of Excellence at NTU as a research scientist. In Mar. 2017, he joined the School of Information Science and Technology, ShanghaiTech University, Shanghai, China, as an assistant professor and establish the VLSI Signal Processing Lab. His research interests include energy-efficient integrated circuits for machine vision and 3D graphics, and other VLSI digital signal processing systems Dr. Lou has published more than 40 technical papers in top journals and conferences such as IEEE TCAS-I, TIP, TPAMI and CICC. Dr. Lou is a senior member of the IEEE, and serves as an Associate Editor of IEEE TCAS-II.
