My primary research interests revolve around the programming language design and implementation. I am particularly interested in the area of software verification for critical code. More specifically, I've been involved in a series of verification projects which target the memory safety of heap-manipulating programs.

HIPimm: Verifying Granular Immutability Guarantees, Partial Evaluation and Program Manipulation, San Diego, California, Jan 2014 [SLIDES]
The implementation of a logic for multiparty session protocols, which offers support for communication specification and verification.
Omega++ is a Coq-certified decision procedure for Presburger arithmetic extended with +infinity and -infinity.
With the use of Omega++, we are now able to
reason about coinductive data
types and infinite data structures (assuming lazy evaluation).
HIPimm - an extension of HIP/SLEEK - offers immutability guarantees at data field level to ensure safe resource sharing for heap-manipulating programs. We can verify program properties such as preservation of data structures shapes in the context of value mutation, flexible aliases, and information leakage prevention.
Automatic verification framework for heap manipulating programs. HIP is a Hoare-style forward verifier for imperative language, able to modularly check functional correctness and safety properties. SLEEK is an automatic prover for separation logic with frame inferring capability.
A platform where students can see HIP/SLEEK in action, or in other words a platform to formally specify and verify C programs.
