research overview

  • Dr. Sankaranarayanan is primarily interested in formal verification techniques, especially for hybrid cyber-physical systems (CPS) which model discrete programs interacting with a continuous environment. In this regard, his work explores the application of techniques from areas such as convex optimization, algebraic geometric methods, combinatorial optimization, symbolic and numerical decision procedures to analyze the behavior of programs and verify key temporal properties such as safety, termination, liveness and stability. His recent work applies Monte-Carlo sampling, rare-event simulations and extreme value theory to develop novel verification techniques for cyber-physical systems is ongoing. Finally, his group is actively extending the scope of verification from verifying the software systems to verifying systems with human operators in the loop using cognitive science techniques to understand and model the behavior of human operators.

Teaching

courses taught

  • COEN 3930 - Engineering Internship/Co-op
    Primary Instructor - Summer 2021
    Students enrolled in this course participate in a pre-approved internship or cooperative education program with an employer that allows them to explore the relationship between theory and practice and demonstrate evidence of significant learning (e.g., academic assignments and employer/sponsor evaluations). Pass/Fail only. Up to 3 credits may apply towards BS degree program's Free Electives (even if student has multiple enrollments in this course and/or COEN 4950). Students should contact the CEAS Extracurricular Programs Manager for more information. Minimum 2.75 cumulative GPA is required.
  • CSCI 3155 - Principles of Programming Languages
    Primary Instructor - Fall 2018 / Spring 2019 / Spring 2020 / Fall 2020 / Spring 2021
    Studies fundamental principles governing the design and analysis of programming languages and the execution models underlying them. Explores a variety of concepts including values, scoping, recursion, higher-order functions, type systems, control structures, and objects.
