Previously:
• (2016 - 2019) Associate Professor in Programming Languages at Oxford University Department of Computer Science and Governing Body Fellow at Kellogg College

• Completed PhD in Informatics at University of Edinburgh in 2010 under Leonid Libkin (supervisor) and Richard Mayr (co-advisor).

Research

I am interested in developing methods using logic and automata for automatically reasoning about programs. At the moment, I have been doing lots of research related to logics over strings. I like applications that arise from web security/optimisation, analysis of large concurrent programs, and databases, to name a few. When doing research, I always try to strike a healthy balance between theory, tool construction, and case studies.

• Current research projects:
  • Algorithmic Verification of String-Manipulating Programs
  • Verification of parameterized concurrent systems:
    • Regular model checking
• Some tools:
  • satcss - one of the best CSS minifiers around at the moment in terms of minification rate. It uses maxsat solvers to iteratively find best rule-merging opportunities that are difficult to identify otherwise.
  • OSTRICH - hitherto the fastest string solver that supports concatenation, replaceall, regular constraints, and other complex string operations like transducers.
  • Sloth - a new string solver that combines concatenation, transducers, replace, regular constraints, and length constraints.
  • SLRP - for automatically verifying liveness for randomised parameterised systems and distributed protocols, and reasoning about two-player reachability games.
  • ParaSymmetry - for automatically verifying/synthesising symmetry patterns and simulation preorder for parameterised systems (see our VMCAI paper).
  • TreePed - for detecting redundant CSS rules in HTML5 applications (see here for a detailed description).
  • ReCount - for verifying integer-manipulating concurrent recursive programs via reversal/synchronisation bounding (see our CAV'11 paper and CAV'12 paper).
• Publications (on Google Scholar|||| on DBLP)
