I am an Associate Professor in the Department of Computer Science at NUS, and a Principal Investigaror at CQT. Before joining NUS/CQT, 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. 


Research Interests:

Broadly speaking, I am interested in discrete structures and their applications in theoretical computer science. In particular, I am interested in the following:

Cryptographers think of me  as a theorist, and theorists think of me as a cryptographer. I like to think of myself as a theorist. Perhaps that makes me a cryptographer :)

Open positions:

I am looking for highly motivated PhD students and postdocs interested in all aspects of computational complexity, discrete mathematics, and algorithms. If you are interested, send me an email.

I am always happy to host very strong PhD students for a 2-3 month internship. If you are interested, please write to me. I typically don't invite undergraduate students for an internship unless you are interested in a PhD position at NUS in the near future.
