Christoph's scientific interests range widely from biology to physics and everything in between. After studying biochemistry, he did his PhD in single-molecule biophysics, followed by a postdoc at the MIT to explore the secret life of microbes.

Xiaozhou Ye

PhD Student

ye_xiaozhou (at)

Xiaozhou studied Biology and Physics in Bejing and will join the lab end of the summer 2020. She will explore how properties of complex microbial communities emerge from the species interactions within them.

Shubham Gajrani

PhD Student

With a background in microbiology and bioinformatics Shubham will join the team end of summer 2020. He will explore how we can use microbial interactions to prevent and fight microbial infections.


Jonas Denk

Visiting PhD Student from LMU Munich 2016

jonas.denk (at)

Jonas is a theoretical physicist by training that dared to try experimental wet lab work. He explored how microbes can kill their own populations by deteriorating the environment which got published in Nature Ecology and Evolution. He is currently a postdoc at Berkeley.

Julien Barrere

Visiting Student from ETH Zurich 2017-2018

jbarrere (at)

Julien studied microbial ecology at ETH Zurich before joining the lab as a visiting student. He explored how interactions between microbes set the biodiversity and stability of complex natural communities. His work got published in Nature Ecology and Evolution. Julien currently works in the Murray Lab, at Harvard, on the evolution of multicellularity.

Jonas Rybnicek

Visiting Student from University of Helsinki 2019
