Assistant Professor at RWTH Aachen
My research interest is in the understanding of bacterial motility dynamics in our gut during the early steps of inflammation and/or infection.

Grognot Lab
I started my new lab at the Institute of Medical Microbiology in RWTH University, in May 2022.
Our research is oriented towards the biophysics of host-microbes interactions, using quantitative methods to assess how microbes (pathogens and commensals) navigate the host environments.
A marine bacterium with a dual flagellar architecture displaying an altered version of the run-reverse-flick motility pattern.

Postdoc Work
At the Taute Lab, we strived to understand how flagellar architecture and environmental properties relate to the resulting bacterial motility pattern, how bacteria achieve chemotaxis with these motility patterns, and how motility patterns might be adapted to specific environments.
To this end, I developped a tool combining a recently developed high throughput 3D tracking method with microfluidically created chemical gradients to implement a simple yet powerful chemotaxis assay.
Simplified schematics of the terahertz ATR setup used to probe epithelial cells in a non-invasive, stain free fashion.

PhD work
During my PhD, I've had the chance to work at the LOB (Laboratory for Optics and Bioscience) at Ecole Polytechnique, under the direction of Guilhem Gallot. I developed and characterized a tool for probing live cell permeabilization dynamics with terahertz light (between far infrared and microwaves).
