Assistant Professor

Office #: 1.202.02
Pillar / Cluster: Information Systems Technology and Design
Research Areas:Computing Theory, Artificial and Augmented Intelligence, Data Science, Networked and Autonomous Systems


Niangjun Chen received his B.S. in Computer Science at the University of Cambridge, and his M.S and Ph.D. in Computer Science at the California Institute of Technology.  His research interests include optimization, machine learning, game theory, and their applications to complex systems such as smart grids, data centers, and transport.   After graduation in 2017, he joined the Institute of High Performance Computing as a research scientist working on the optimization of logistics and the modeling and simulation of the transport systems. Since September 2020, he is an Assistant Professor at the Singapore University of Technology and Design. He has a joint appointment at the Institute for High Performance Computing at the Agency for Science, Technology, and Research (A*STAR).
