Short Bio

I am a Visiting Assistant Professor at the Department of Computer Science and Engineering of the Hong Kong University of Science and Technology (HKUST). Before assuming this position, I was a post doctoral fellow at the Department of Computer Science and Engineering of the Chinese University of Hong Kong, in the research group of Prof. Yufei Tao. I received my PhD degree in Computer Science at HKUST, under the supervision of Prof. Dimitris Papadias.
