The Guardol Language and Verification System

Abstract:

Guardol is a domain-specific language designed to facilitate the construction of correct network guards operating over tree-shaped data.  The Guardol system generates Ada code from Guardol programs and also provides specification and automated verification support.   Guard programs and specifications are translated to higher order logic, then deductively transformed to a form suitable for a SMT-style decision procedure for recursive functions over tree-structured data. The result is that difficult properties of Guardol programs can be proved fully automatically.

Biography:

Dr. David S. Hardin has made contributions in the areas of formal methods, computer architecture for High Assurance systems, as well as real-time and embedded Java.  He is currently a Principal Engineer in the Advanced Technology Center at Rockwell Collins, where he has served as Principal Investigator for several U.S. DoD Research and Development programs.  He is the editor of the book Design and Verification of Microprocessor Systems for High-Assurance Applications (Springer 2010), and a co-author of The Real-Time Specification for Java, as well as the Java 2 Micro Edition Connected Device Configuration/Foundation Profile standards.  He is author or co-author of more than 30 peer-reviewed publications, and is a co-inventor on nine U.S. patents.  In 1999, Dr. Hardin co-founded aJile Systems, a startup company focused on real-time and embedded Java technology, and served as aJile's Chief Technical Officer from 1999 to 2003.  Dr. Hardin was selected as a Rockwell Engineer of the Year for 1997 for his contributions to the development of the world's first Java microprocessor. His academic career includes BSEE and MSEE degrees from the University of Kentucky, and a Ph.D. in Electrical and Computer Engineering from Kansas State University, in 1989.  Dr. Hardin is a proud native of the Commonwealth of Kentucky, and is a Kentucky Colonel.
