From bugs to bubbles

A quick introduction

My name is François Peaudecerf, I am a post-doctoral researcher at the Institute for Environmental Engineering of the ETH Zürich in the group of Prof. Roman Stocker.

Before joining ETH, I obtained my PhD at the Department of Applied Maths and Theoretical Physics (DAMTP) at the University of Cambridge (UK) in the group of Prof. Ray Goldstein.

My main research interests include microbial interactions, microswimmers and soft matter physics, in particular air-water interfaces. I investigate these topics by combining experiments with mathematical modelling.

Paper published in PRE!

20 February 2018

Our work on microbial mutualism at a distance has just been published in Physical Review E! We present how the geometry of diffusive bridges between mutualistic microbes modifies their population dynamics and interactions.

Marie Curie proposal successful!

29 January 2018

The project I submitted for a Marie Skłodowska-Curie Individual Fellowship was accepted: during this 2 year project, starting in June, I will investigate the interaction between bacteria and rising bubbles in the ocean.

Maze video awarded prize at DFD!

20 November 2017

Our video "Soap opera in the maze: geometry matters in Marangoni flows" has been named an Award Winner at the Gallery of Fluid Motion of the 70th APS DFD meeting in Denver, Colorado US. It is also featured in a post on FYFD. The video is also here.
