Patrick Totzke

Hey there! I am a Professor at the Department of Computer science, the University of Liverpool.

research

I work at the intersection of maths and computer science and specialize in the foundations of verification and computation. My interests include

• Algorithmic game theory, especially strategy complexity and infinitary games and MDPs on graphs;
• Decidability and complexity of verification problems such as (bi)simulation, language inclusion, model checking and synthesis;
• Counter automata, vector addition systems / Petri nets and process algebras;
• Computational logics with fixed-points, temporal or probabilistic modalities and associated games.
• Time-sensitive models: timed automata and languages, timed nets and games, and temporal graphs.

short bio

As of 2024, I am a full professor (personal chair) at the University of Liverpool. I joined Liverpool as a lecturer in 2018 and before that I did postdocs at the LFCS in Edinburgh (from 2016) and spend a year each at the University of Warwick (2015) and LaBRI in Bordeaux (2014). I hold a PhD from the University of Edinburgh and a diploma (Dipl. Inf.) from the University of Hamburg where I grew up.

In my spare time I attempt to play the trumpet and maintain a healthy appreciation of good whisky. I am overly passionate about free software. I have a ha-index of 80 and happily support the initiative.
