My research focus is on spatial interactions in biological systems at different length scales. For this, I apply and adjust techniques from data analysis and mathematical modelling such as image analysis, spatial statistics, agent-based modelling and machine learning. I enjoy working in an interdisciplinary environment and utilising the different perspectives for solving interesting research questions.

Research

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”. 

Projects

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

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.
