Research Interests

  • Algorithms and data structures
  • Succinct data structures for representing trees
  • Compact in-memory representation of XML
  • XML compression
  • Efficient XPath query algorithms

I am currently researching both static and dynamic succinct data structures to represent ordinal trees, and applying these techniques to the problem of efficiently representing XML documents in computer memory.

I am a member of the Algorithms and complexity group here in the Department of Computer Science.

My PhD supervisor is Professor Rajeev Raman.
