21 August 2017 – NUS Computing welcomes seven new faculty members—three in the Department of Computer Science and four in the Department of Information Systems and Analytics. They are:


Department of Computer Science

Dr. Trevor E. Carlson obtained his PhD in Computer Science from Ghent University, Belgium in 2014. He obtained his Master of Science and Bachelor of Science degrees in Electrical and Computer Engineering from Carnegie Mellon University, USA in 2003 and 2002, respectively. Prior to joining the Department, Dr. Carlson was a Postdoctoral Researcher at Uppsala University, Sweden.

Dr. Carlson has over 13 years of computer architecture experience in both industry and academia. He co-developed the Sniper Multi-Core Simulator, which is being used by hundreds of researchers to evaluate the performance and power-efficiency of next generation systems. His work on simulation, sampling and modeling has seen a Best Paper Award and two nominations for Best Paper. Dr. Carlson’s research interests include highly-efficient microarchitectures, hardware/software co-design, performance modeling and fast and scalable simulation methodologies.

Department of Information Systems and Analytics

Dr. Joseph Jay Williams' research agenda is to create intelligent self-improving systems that conduct dynamic experiments to discover how to optimize and personalize technology, helping people learn new concepts and change habitual behavior. This requires using computational cognitive science and Bayesian statistics to bridge human-computer interaction with machine learning, with applications to education and health behavior change.  More information on Dr. Williams’ research can be found at http://www.josephjaywilliams.com/research-overview?pli=1  

Before joining Information Systems and Analytics as an Assistant Professor, he held Research Fellow positions in digital education groups at Harvard and Stanford, and received his PhD in Computational Cognitive Science from UC Berkeley.
