Stephen     F.     Siegel

Stephen Siegel photoI am an associate professor in the Department of Computer and Information Sciences at the University of Delaware. I also hold a joint appointment in the Department of Mathematical Sciences.

My current research interests include (1) formal methods for software verification, (2) parallel and scientific computing, and (3) applications of (1) to (2). As a recovering mathematician (having worked in the cohomology and representation theory of finite groups), I am always looking for new applications of mathematics and logic to problems in computer science.

I direct the Verified Software Laboratory, which conducts research and develops tools targeting the problems above. CIVL, a verifier for parallel scientific/HPC programs, is our flagship product. Our software, publications, and experimental artifacts are all available on the VSL web page.

Teaching

I teach the following courses (semi-)regularly:
  • CISC 404/604, Logic in Computer Science
  • CISC 372, Parallel Computing. MPI, OpenMP, Pthreads, CUDA, fundamental concepts of concurrency for both message-passing and shared-memory models. Learn more about the course here.
  • CISC 414/614, Formal Methods in Software Engineering. This class gives an overview of formal methods, with emphasis on practical applications of tools such as Alloy, Spin, and Frama-C.
  • CISC 475/675, Advanced Software Engineering/Software Engineering Principles and Practices. This is a project-based course, going through all stages of the software lifecycle, including requirements engineering, design, coding, testing and verification.
  • CISC 849/879, advanced topics. Topics have included Advanced Topics in Software Verification, Abstract Interpretation, Advanced Parallel Computing, and Model Checking.
  • CISC 366/466, Independent Study. For undergraduate students who want to take part in the research of the VSL. Contact me if you are interested.
