Tim Wahls

Courses Taught, Spring 2012
COMP 131 Computer Science I
COMP 378: Database Systems

Education
B.S. 1990, Computer Science, Iowa State University
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 specifications (especially 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, object-oriented programming, networking, Java, Visual Basic, C and UNIX, algorithms and simulation.
