Center for Computational and Theoretical Biology

Supramolecular and Cellular Simulations

We work on data-driven modelling and simulations of processes at the subcellular, multicellular and multitissue scale. For the data analyses, we develop and apply tools that range from classical statistics to machine learning approaches. To test hypotheses about interactions of structure and function at the different scales, we use mathematical modelling and simulations. In particular, we use on- and off-lattice agent-based modelling in two and three spatial dimensions as well as three-dimensional morphological modelling with Blender. 

We are part of the DFG priority program SPP 2332 "Physics of Parasitism”, the ESF project "Forum KIdT - Künstliche Intelligenz und digitale Transformation"  and associated to the SFB / TRR 225 “Biofabrication”


Beta-Tester for julia programming course

We are looking for people that are interested in learning the programming language julia.

If you want to have a go, feel free to download our course and work on one or more parts of it. We would appreciate it a lot if you would let us know any feedback that you might have. Thank you!


We offer internships, Bachelor and Master theses as well as Zulassungsarbeiten (Lehramt) from October 2024

In general, we are looking for highly motivated candidates, who are team-oriented, willing to learn and work independently and precisely:

  • Keen interest in one of our projects, quantitative data analysis and/or mathematical modelling, and programming (prior knowledge in any of these is not required)
  • Enthusiasm for communication with experts from other disciplines 

We offer a friendly working environment, excellent computing infrastructure and supportive supervision.

If you are interested, please contact Sabine Fischer for further details.
