I am an assistant professor at the National University of Singapore working to develop high-efficiency microarchitectures that can meet the performance and needs of future IoT and server applications. To do this, we explore a number of computer-architecture related areas, from energy-efficient processors, to secure chips and neuromorphic accelerators. The foundation for our architecture research comes from our experience in fast and accurate simulation methodologies and analytical modeling. Additionally, I co-develop the Sniper Multi-Core Simulator.

If you are interested in conducting research into energy-efficient processors, secure computing platforms, AI accelerators, programmable hardware, or simulation methodologies, contact us or see our open positions page for details.
