Teaching
Lectures
I coorganise several lectures offered by the Chair for Software Engineering.

CyberPhysical Systems I: Discrete Models WS23/24 WS22/23 WS21/22 WS20/21 WS19/20
This lecture is based on the book Principles of Model Checking by Baier and Katoen, and introduces students to formal modeling of cyberphysical, reactive systems as transition systems. We discuss different modeling formalisms, specifications in the form of lineartime properties, and the automatatheoretic approach to lineartime (LTL) model checking.

CyberPhysical Systems II: Program Verification SS24 SS22 SS21 SS20 SS19
In this lecture, we develop the syntax and formal semantics of a simple imperative programming language. We use this language to introduce students to a variety of different approaches to program verification, from Hoare logic, over predicate transformers and symbolic execution, all the way to CEGARbased verification algorithms such as predicate abstraction and trace abstraction.
In the current semester (summer semester 2024), I am the lecturer for this course.

Theoretical Computer Science (dt: Theoretische Informatik) SS23 SS22
This course introduces students to the foundations of computation. It covers formal languages, grammars, the Chomsky hierarchy, automata theory, Turing machines, decidability and complexity theory.
Seminars
I frequently supervise students in the different seminars offered by the Chair for Software Engineering.
 Classical Articles of Program Analysis (dt: Klassische Artikel der Programmanalyse, BSc Proseminar) WS21/22 WS20/21 WS19/20
 Automata Theory (dt: Automatentheorie, BSc Proseminar / Seminar) WS22/23 SS21 SS20
 Advanced Topics in Program Analysis (MSc seminar) WS20/21
In our seminars, students are given source material on their assigned topic (either a research paper, or a book chapter). The students then write a proposal, describing their plan for a 25min research talk on the topic. Students typically review one or more proposals by other students. The talks are either given throughout the semester, or as a “block seminar” in 12 days near the end of the semester.
Student Projects
I have supervised a number of student projects revolving around program analysis and automata theory. Such projects typically involve a theoretical component (e.g. design / modification and correctness proof of some algorithm) and an implementation and evaluation component in the context of the program analysis and automata theory framework Ultimate.
If you are interested in a project or thesis, send me an email. You can find a list of possible topic areas in the Ultimate wiki.
