I am a final-year PhD student in the Multicore Programming group at Imperial College London. Next autumn, I will join the Programming Principles and Tools group at Microsoft Research Cambridge as a Research Software Development Engineer.

My research interests include programming language design and static/dynamic program analysis, especially applied in the context of complex asynchronous reactive software systems. For my PhD thesis, I created P#, a new asynchronous programming language co-designed with static data race detection and systematic testing techniques, which is now used inside Microsoft. I also developed Whoop, a static analyzer that can efficiently detect data races in Linux device drivers.

I was honored to be selected as one of the 15 finalists in the UK ICT Pioneers 2015 competition by EPSRC for my work on P#!

Projects.

I am a key contributor / lead developer in the following projects:

  • [git] P#, a language that simplifies developing, analysing and testing asynchronous programs, such as web services and distributed systems.
  • [git] Whoop, a tool that (i) automatically analyses Linux device drivers for data races and (ii) exploits the race-related information to accelerate Microsoft's Corral, an industrial strength bug-finder for concurrent programs.
  • [git] lockpwn, a static lockset analyser for pthread C programs. This tool largely reuses the static lockset analysis and race checking APIs of Whoop, but applies the technique on pthreads instead of device drivers.
  • Dungeon Story, a Puzzle/RPG game that I developed (as a hobby project) during summer 2012. The game is available worldwide in the iOS App Store, it has been downloaded by more than 110,000 users, and has hundreds of 4.5/5 star ratings.

I have also contributed to the following projects:

  • [git] SMACK, a bounded software verifier for C programs.
  • [git] GPUVerify, a tool for formal analysis of GPU kernels written in OpenCL and CUDA.
  • [git] Boogie, an intermediate verification language.
