Research interests

I am currently working as Post-Doc in the group of Prof. C. Hemelrijk on collective behaviour of fish schools and bird flocks.

A collective motion pattern which is often observed in fish schools is the so-called milling (i.e. circular motion, also called vortex state). I am currently studying the emergence of milling in minimal models, in order to understand the fundamental mechanisms and ingredients of milling formation.

Already during my Master and PhD in theoretical physics, I have worked on collective behaviour. In particular, I worked on models and simulations of the run-and-tumble motion of E. coli bacteria and self-propelled rods, investigating transport problems, sorting techniques, and ratchet phenomena.
