Research: 

Software is increasingly involved in our lives; software controls physical systems ranging from microwave ovens and watches to nuclear power plants, aircraft, and cars. Computer-related failures can, in many of these applications, have catastrophic effects.

My research group, the Critical Systems Research Group (CriSys), is conducting research in software engineering and is investigating methods and tools to help us develop software with predictable behavior free from defects.

Research in this area spans all aspects of system development ranging from concept formation and requirements specification, through design and implementation, to testing and maintenance. In particular, we are currently investigating model-based software development for critical systems.

Specifically, we are focusing on how to use various static verification techniques to assure that software requirements models possess desirable properties, how to correctly generate production code from software requirements models, how to validate models, and how to effectively use the models in the testing process.

Interests: 

Software engineering and safety critical systems.

Specification Based Prototyping of Control Systems

The capability to dynamically analyze, or execute, the description of a software system early in a project has many advantages; it helps the analyst to evaluate and address poorly understood aspects of the system behavior, improves communication between the different parties involved in specification effort, allows empirical evaluation of alternative solutions, and is one of the more feasible ways of validating a system's behavior. In this paper, we focus on an approach to simulation and debugging of formal software specifications for control systems called specificationbased

Requirements Capture and Evaluation in Nimbus: The Light Control Case Study

Evaluations of methods and tools applied to a reference problem are useful when comparing various techniques. In this paper, we present a solution to the challenge of capturing the requirements for the Light Control System case study, which was proposed before the Dagstuhl Seminar on Requirements Capture, Documentation, and Validation in June of 1999.

Specifying and Analyzing System Level Inter-Component Interfaces

In control systems, the interfaces between software and its embedding environment are a major source of costly errors. For example, Lutz reported that 20% - 35% of the safety related errors discovered during integration and system testing of two spacecraft were related to the interfaces between the software and the embedding hardware. Also, the software's operating environment is likely to change over time further complicating the issues related to system-level inter-component communication. In this paper we discuss a formal approach to the specification
