Dr. Shoushun Chen received his B.S. degree from Peking University, M.E. degree from Chinese Academy of Sciences and Ph.D degree from Hong Kong University of Science and Technology in 2000, 2003 and 2007, respectively. He held a post-doctoral research fellowship in the Department of Electronic & Computer Engineering, Hong Kong University of Science and Technology for one year after graduation. From February 2008 to May 2009 he was a post-doctoral research associate within the Department of Electrical Engineering, Yale University. In July 2009, he joined Nanyang Technological University as an assistant professor.

Before joining NTU, Dr. Chen had been actively involved in a number of research projects related to VLSI implementation of microprocessor, circuits and systems design for vision sensor, algorithmic design for image processing. In Chinese Academy of Sciences, Dr. Chen was a key backend designer of "Loongson-1"(龙芯一号) CPU which is the first general purpose CPU designed in China. In Hong Kong, his research was mainly related to design and VLSI implementation of ultra-low power and wide dynamic range CMOS image sensors using time encoding techniques and asynchronous readout strategies. At Yale, his work was toward a combination of smart vision sensors and energy-efficient algorithm.

In NTU, he leads a research team, namely the Smart Sensors group. They aim to foster research, development, and industrial dissemination of knowledge related to the emerging field of sensors and associated microsystems. They target the combination of custom designed sensor and energy-efficient signal processing algorithms, making it possible to simultaneously increase the computational throughput and efficiency, therefore to translate this success to cost-effective systems with the potential for broad application areas such as Satellite, UAV and UGV. The activity is genuinely multidisciplinary, leveraging knowledge and expertise from fields such as mixed-signal integrated circuits, signal processing algorithms and their VLSI implementation.

Dr. Chen is a senior member of IEEE. He serves as a member, Secretary-Elect of Sensory Systems Technical Committee, IEEE Circuits and Systems Society (CASS); Associate Editor of IEEE Sensors Journal; Program Director (Smart Sensors) of VIRTUS, IC Design Centre of Excellence; Regular reviewer for a number of international conferences and journals such as TVLSI, TCAS-I/II, TBioCAS, TPAMI, Sensors, TCSVT,etc.

Dr. Chen is a founder of CelePixel Technology.
