M.S. 1992, Computer Science, Iowa State University
Ph.D. 1995, Computer Science, Iowa State University
Research and Teaching Interests
My main research interests
are in specification language design and semantics (especially for
object-oriented specification languages), and in the execution of formal
the applications of constraint logic programming techniques in executing
formal specifications). I have also done some work in linguistic content
analysis and computer science education.
My teaching specializations are in software engineering and programming
languages. I have also taught courses in database, compilers, constraint
programming, networking, Java, Visual Basic, C and UNIX,
algorithms and simulation.
