My main research interest is methodology to support the development, validation, and evolution of complex software systems. I am currently investigating techniques for advanced software design, software testing, software security validation, intrusion detection, and mining of software repositories. I currently teach software engineering, computer security, and advanced software design.

I am an Associate Professor of Computer Science in the Electrical Engineering & Computer Science Department at Case Western Reserve University in Cleveland, OH, where I have been a faculty member since 1989. I received a Ph.D. in Computer Science from the University of Massachusetts, Amherst. I have conducted research on software engineering methodology and related topics for nearly twenty years and have many publications in these areas. I have also worked extensively with industry on software engineering projects. I have taught software engineering, computer security, distributed systems, computer networks, software testing, compiler design, and algorithm design.
