3D tracking of micron-sized particles
Group: Systems Biology
We have developed a simple, robust, and broadly applicable, high-throughput 3D tracking method based on computational image analysis, which requires only a standard phase contrast microscope, a camera and a PC.

Biochemical computing and cellular information transmission
Group: Biochemical Networks
In our group we combine ideas from statistical physics and stochastic thermodynamics to study biochemical computing and cellular information transmission, using analytical theory and novel computer simulation techniques.

Developmental biology, nematode worms, organoids, microscopy, image analysis and machine learning
Group: Quantitative Developmental Biology
We use advanced microscopy, quantitative image analysis and mathematical modelling, to understand how cells make decisions during development, how timing of development is controlled and complex tissues, like the human intestine, renew themselves.

Particle-based simulations of diffusion in complex geometries and mixed boundary conditions
Group: Theory of Biomolecular Matter
We develop state-of-the-art stochastic approaches to solving diffusion problems involving non-trivial geometries (curved surfaces, diffusion bottlenecks, …) with mixed Robin type boundary conditions, which do not require spatial discretisation.
- reaction diffusion systems
- thermal design
Cellular dynamics in organoids, protein synthesis and folding
At the molecular level, we use optical tweezers and single-molecule fluorescence to study how chaperones fold amino-acid chains into functional proteins. At the cellular level, we use time-lapse microscopy and image analysis to understand how organoids self-organise.
