I am currently a PhD candidate in Computer Science at the Australian National University. I am a member of the Algorithm and Data group whose main focus is design and analysis of combinatorial algorithms. I received my Master's degree at the Amirkabir University of Technology, where I studied theory of computation.

My PhD is about designing efficient and scalable algorithms for large-scale complex networks, including social networks and collaboration networks. My main focus is on community structure and community search at scale, hierarchial structure of communities, identifying structural hole spanners and influential members of social networks, etc. My main research interests are:

  • Algorithm design and data structures
  • Graph theory and large-scale networks
  • Database systems and graph databases
  • Social network analysis and mining
