I am a PhD student in the Software Modeling and Verification Group headed by Professor Joost-Pieter Katoen. Moreover, I am an associated doctoral researcher in the research training group UnRAVel.
My research focuses on automatic formal analysis of probabilistic systems, both from a theoretical and practical point of view. More specifically, my research interests include:
- Probabilistic Model Checking, in particular stochastic games and probabilistic push-down systems
- Parametric Probabilistic Models, that is, models that are not fully specified but depend on some parameters
- Probabilistic Programs, in particular invariant-based and other rule-based approaches
If you are interested in writing a Bachelor/Master’s thesis in any of the areas mentioned above, don’t hesitate to contact me. You can also check our list of open topics. I am currently supervising or have supervised the following thesis projects:
Ongoing thesis projects
- Compositional Control-Flow Reduction for Probabilistic Model Checking – Leon Barth, Bachelor’s thesis.
- Implementation of an LTL Model Checker for Probabilistic Push-Down Automata – Laura Bamberger, Bachelor’s thesis.
Past thesis projects
- Automata-based Model Checking of Recursive Systems – Christina Gehnen, Bachelor’s thesis. 2020.
Christina has received an award from the Fachgruppe Informatik for her thesis.
- Probabilistic Programming WS20/21
- Probabilistic Programming (Seminar) WS20/21
- Datenstrukturen und Algorithmen SS20
- Introduction to Program Analysis (Proseminar) SS20
- Our paper Generating Functions for Probabilistic Programs (joint work with Kevin Batz, Lutz Klinkenberg, Benjamin Lucien Kaminski, Joost-Pieter Katoen and Joshua Moerman) has received the best paper award at LOPSTR 2020.
- I was awarded the Springorum Medal in 2020 for receiving a master’s degree with distinction.
