I am a senior researcher in the School of Computer and Communication Sciences at EPFL. Before this, I spent two years as a postdoctoral researcher at the Department of Computer Science at New York University from September 2012 to August 2014. I completed my PhD under the guidance of Prof. Ueli Maurer at ETH Zurich in February, 2012. 

I will be joining as an Assistant Professor in the Department of Computer Science at NUS, and a Principal Investigaror at CQT in Fall, 2016.
