I have been a PhD student at the Software Modeling and Verification Group since June 2015.

You can also find me on DBLP and Google Scholar.

Research interests

  • Model checking of quantitative (parameterised) systems
  • Formal aspects of reliability engineering, in particular fault trees
  • SMT-solving for real arithmetic
  • Formal modelling of real-world systems

Tool support

Research in automated verification is impossible without proper tool support.  Over the years, I’ve been involved in the development of

  • The SMT-solver SMT-RAT (2011 — 2015)
  • The arithmetic library carl (2012 — 2015) and its python bindings pycarl (since 2016)
  • Compass (2014)
  • The Markov Chain Parameter Synthesis Framework PROPhESY (since 2014)
  • The Probabilistic Model Checker Storm (since 2014) and its python bindings stormpy (since 2016)

 

B.Sc or M.Sc theses

I’m always looking forward to work with students. If you’re looking for a thesis in one of the areas above, do not hesitate to contact me! Some ideas are given in our list of open topics.

Previously, I supervised the following theses (chronological order):

  • Tom Janson, Accelerated Model Repair using Heuristic Analysis of Subsystems (BSc)
  • Tim Quatman, Multi-Objective Model Checking for Markov Automata (MSc)
  • Ronja Nocon, Pattern-based detection of Monotonicity in Dynamic Fault Trees (BSc) [together with Matthias Volk]
  • Michael Deutschen, GSPN Semantics for Dynamic Fault Trees (MSc) [together with Matthias Volk]
  • Dustin Jungen, Repairs in Dynamic Fault Trees (BSc) [together with Matthias Volk]
