I am faculty at the Complexity Institute at the School of Physical and Mathematical Sciences, Nanyang Technological University. I also hold a joint appointment at the Centre for Quantum Technologies at the National University of Singapore. My primary research interest is in the interface between physics, computation, and complexity.

The laws of physics can tell us what class of functions are computable and what problems are either easy of intractable to solve. They shed light on how information is processed with our reality. On the other hand, the study of computation can reveal properties that unify otherwise seemingly desperate physical systems, for many systems may operate of drastically different physical processes, and yet have coinciding properties when it comes to the processing of information. Currently, my focus is on two topics that follow this theme:

- How can we exploit quantum mechanics to construct the simplest simulators of complex physical processes?
- How can we characterize non-classical correlations, that are the resource for quantum speed-up?

In my spare time, I enjoy the Game of Go and hold a 5 Dan Rank from the Singapore Weiqi Association.
