Sankaranarayanan Receives NSF CAREER Award

 

February 2010

Assistant Professor Sriram Sankaranarayanan was recently awarded a Faculty Early Career Development (CAREER) Award by the National Science Foundation. The Program is a Foundation-wide activity that offers the NSF's most prestigious awards in support of the early career-development activities of those teacher-scholars who most effectively integrate research and education within the context of the mission of their organization. Such activities build a firm foundation for a lifetime of integrated contributions to research and education. The project is titled Automatic Analysis of Cyber Physical Systems: Bridging the Gap between Research and Industrial Practice.

Cyber-physical systems are responsible for numerous control tasks in safety-critical systems such as automobiles, avionics, medical devices, and power distribution systems. Guaranteeing the correctness of these systems is of the utmost importance. However, existing verification and validation techniques have, thus far, fallen short of addressing this important challenge.

This project will investigate verification techniques for analyzing large and complex cyber-physical systems. The project will develop rich modeling formalisms that are capable of capturing realistic system designs at the right levels of abstraction. These formalisms will form the basis for verification techniques that can be used to pin-point functional defects in cyber-physical systems. Specifically, the project focuses on techniques for detecting harmful numerical precision loss in control systems implemented using fixed and floating point numbers. Finally, the project addresses the challenge of verifying complex non-linear systems using interval analysis, convex optimization and symbolic decision procedures. The results of this research are available to the community in the form of open-source tools. These tools will directly support the verification of complex systems.

The approximately $460,000 award is expected to fund the research over a five-year period.
