I am an Assistant Professor in the Department of Computer Science at NUS, and a Principal Investigaror at CQT since August, 2016. Before this, I was a post-doctoral researcher for two years each in the School of Computer and Communication Sciences at EPFL, and the Department of Computer Science at New York University. I completed my PhD under the guidance of Prof. Ueli Maurer at ETH Zurich in February, 2012. 

I am looking for highly motivated PhD students and post-docs. If you are interested, write to me. Also, I am particularly interested in having interns who have done well in the mathematics/informatics olympiad at the national or international level.
