Research

I am a PhD student at the Software Modeling and Verification Group (MOVES) headed by Professor J.-P. Katoen since December 2015. Since October 2017, I am a doctoral researcher (Stipendiat) within the Research Training Group UnRAVeL.
My research interests include:

  • Analysis of dynamic fault trees (DFTs)
  • Verifiying fault trees for railway safety (see UnRAVeL project AP4)
  • Model checking of (parametric) probabilistic systems

Tool support

I am actively involved in the development of the following tools:

  • The probabilistic model checker Storm and its python bindings stormpy
  • The python bindings pycarl for the arithmetic library CArL
  • The parameter synthesis framework for parametric Markov chains PROPhESY

Bachelor/Master Theses

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

In the past, I have been supervising the following theses:

  • Dustin Jungen, Repairs in Dynamic Fault Trees, 2017, Bachelor thesis (together with Sebastian Junges)
  • Michael Deutschen, GSPN Semantics for Dynamic Fault Trees, 2017, Master thesis (together with Sebastian Junges)
  • Ronja Nocon, Pattern-based detection of Monotonicity in Dynamic Fault Trees, 2016, Bachelor thesis (together with Sebastian Junges)

Teaching

I am currently involved in the following teaching activities:

Awards

Our paper “Automated Fine Tuning of Probabilistic Self-Stabilizing Algorithms” (joint work with Saba Aflaki, Borzoo Bonakdarpour, Joost-Pieter Katoen and Arne Storjohann) won the Prof. C.V. Ramamoorthy Best Paper Award at the 36th IEEE Int. Symposium on Reliable Distributed Systems (SRDS) in Hongkong. The paper presents automated techniques to find the probability distribution that achieves minimum average recovery time for randomized distributed self-stabilizing algorithms.
