|I am an assistant professor in the Department of Computer Science and Department of Mathematics at the National University of Singapore, and an affiliate with the Institute of Data Science. I am also a recipient of the National Research Foundation (NRF) Fellowship.
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 machine learning, information theory, and high-dimensional statistics. Please see my research and publications pages for further information.
