Biography

I am a full-time teaching assistant in the school of computing, and a part-time PhD candidate under the supervision of Associate Professor Jin Song Dong.

My research area centers on software engineering, including requirement specification, system-level design and formal verification. I am particularly focusing on applying rigorous analysis techniques to improve the reliability and robustness of large-scale software systems embedded in safety-critical environment with real-time constraints.

• Machine-assisted Proof Support for Interval-based Specification Languages: I have developed a novel verification system which provide a high level of automation for rigorously analyzing formal models of embedded real-time computing systems.
  The verification system is built upon a popular generic theorem prover, Prototype Verification System (PVS), to support two prominent interval-based specification languages, Timed Interval Calculus (TIC) and DC (Duration Calculus).
  Using the verification system, we can deal with complex proofs of TIC/DC models, which may involve mathemtical reasoning (e.g., integration and differentiation) and arbitrary (infinite) intervals over continuous time, in a way similar to their corresponding manual arguments, where the translation from TIC/DC models to PVS specifications and proof obligation at at low levels are automatically accomplished.
• Enhance the design confidence of Simulink: I have constructed a formal framework to model and validate Simulink diagrams by exploiting TIC, based on our developed verification system.
  Simulink is one of the most popular commercial products of the MathWorks for graphically specifying and simulating embedded systems. The framework can handle a variety of dynamice systems modeled in Simulink, such as continuous, discrete or hybrid systems. It can automatically transform Simulink diagrams to TIC models, and the transformation faithfully preserving the functional and timing aspects. Moreover, the framework can enlarge design spaces of Simulink and check system behavior beyond Simulink.
