Short Bio

I am a Senior Research Scientist at the Intel Parallel Computing Lab (since February 2014), and a member of the Intel Science and Technology Center for Big Data, which is situated at MIT CSAIL. Prior to joining Intel, I was a Visiting Assistant Professor at the Department of Computer Science and Engineering of the Hong Kong University of Science and Technology (HKUST), between September 2011 and January 2014. I received my PhD degree in Computer Science at HKUST, under the supervision of Prof. Dimitris Papadias, whereas I spent a year and a half as 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.
