My research is driven by quantitative considerations in biology with a systems point of view.
The biological questions in the focus of my research are on mechanisms resulting from networks of interacting components. Some of the mechanisms I have studied in the past are related to cancer pharmacology, diabetes, synthetic biology, and DNA computing.
My research in systems and synthetic biology makes extensive use of simulation models and formal methods from computer science. I am especially inspired by the idea of computer-aided design of synthetic biology applications.The interplay between practical problems in biology and the theoretical aspects of computer science is in the heart of my research. I aim at bridging theoretical considerations in computer science and applied mathematics to solve practical problems.
In the first chapter of this book, I describe how mathematical modelling realises a computer-aided design vision in creating living technologies based on microorganisms. The aim here is to make synthetic biology a field of engineering rather than a purely experimental discipline based on trial and error.

[LINK] Causal Analysis in Bio-pathways via Stochastically Simulated PerturbationsAutomated reasoning is hard, so it is no wonder that LMMs struggle with it. Yet, automated provers are pushing the envelope for industrial applications these days. Can we achieve competitive results with analytic provers? That is what I investigate in this paper.
