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.

Research Interests

While at Intel and MIT, I built the TileDB array database system.

My other research interests include:

  • Array Databases
  • Massively Parallel Architectures
  • Verifiable computation
  • Searchable encryption
  • Private information retrieval
  • Differential Privacy
