About Me
| I am an assistant professor in the Department of Computer Science, the Department of Mathematics, and the Institute of Data Science at the National University of Singapore.
Prior to joining, I was a post-doc in LIONS, EPFL (Sept. 2014 - Sept. 2017), and a PhD student at the University of Cambridge (Oct. 2011 - Aug. 2014). My research interests are in the areas of information theory, machine learning, and high-dimensional statistics. Please see my research and publications pages for details. |
