Our mission
The Mathijssen lab is interested in exploring the physics of life: we combine experimental and theoretical techniques across the disciplines of physics and biology.
Our main goals are to unravel the physics of pathogens, to design biomedical materials, and understand the collective functionality of living systems (out of equilibrium). To solve these multi-scale problems we use methods from microbiology, fluid mechanics, omics, statistical physics, microscopy and information theory. Recent themes include hydrodynamic communication, pathogen clearance in the airways, tuning upstream swimming of microrobots, and bacterial contamination dynamics.
These questions are both fundamental in nature (e.g. How can an intelligent system arise from the collective dynamics of its basic components?) and directly applied to our society (e.g. What is the probability of SARS-CoV-2 transmission within a food supply chain?). Our enthusiasm for research is driven by curiosity and the need for solutions that connect science with the challenges of the world we live in. Besides research, we like organising community events, lab visits and science hikes.

Join our team
Scientific innovation depends on the diversity of our team, in my opinion. We welcome people regardless of who they are and where they come from. We support each other’s differences, because everyone has unique talents.
Applications are invited from a broad range of academic backgrounds. We are looking for undergraduate, graduate and postdoctoral researchers interested in (learning) the fields of biological physics, soft matter, physical biology, chemistry, engineering, mathematics and data science. Both experimental and theoretical or computational research positions are currently available: Click here to find out more and join us!
NEWS: Editor’s choice paper in Physical Review Letters:
Collective entrainment and confinement amplify transport by schooling micro-swimmers
Chenyu Jin, Yibo Chen, Corinna C. Maass, Arnold J. T. M. Mathijssen
Micro-swimmers can serve as cargo carriers that move deep inside complex flow networks. When a school collectively entrains the surrounding fluid, their transport capacity can be enhanced.

Active carpets drive non-equilibrium diffusion and enhanced molecular fluxes
Francisca Guzmán-Lastra, Hartmut Löwen, Arnold J. T. M. Mathijssen
Fick’s laws describe the essential physics of diffusion, but it is challenging to extend them to systems out of equilibrium. The authors derive the diffusivity of particles near active carpets – a surface covered with hydrodynamic actuators, which provides a framework for transport in living matter.
