'Collective transport by algae' manuscript accepted in Small!
20 January 2026
Our article on the collective transport of large particles with microalgae was accepted in Small! Jointly carried out with Taha Laroussi in LadHyX, this work shows some promising insights for depollution using microorganisms.
26 November 2025
Our article on the erosion-based homogenisation of microfluidic networks is now out in Physical Review X! It was the fruit of a great collaboration with Swarnavo Basu from Karen Alim's group in Munich, while I was working in LadHyX with Gabriel Amselem.
Angéline Girard joins us for a PhD!
3rd November 2025
Angéline Girard is starting her PhD in Exeter, after being awarded a joint studentship between the University of Exeter and Université Paris-Saclay. She will work on the motility of excavates in complex environments. Happy to be her co-supervisor alongside Kirsty Wan in LSI and Harold Auradou in FAST!
New postdoctoral position in Exeter!
4th November 2024
I am delighted to join Kirsty Wan's group in the Living Systems Institute in Exeter, in the South-West of the UK! I will be investigating the behaviour of unicellular eukaryotes such as excavates and diatoms.
Research interests
I am a physicist specialised in fluid mechanics, with a strong interest in hydrodynamics and microfluidics. I am particularly interested in using microfluidics to better understand swimming microorganisms, for instance the interactions of such living microswimmers (bacteria, microalgae...) with their environment.
About me
Currently a Postdoctoral Research Fellow at the Living Systems Institute (University of Exeter, United Kingdom) with Kirsty Wan, I am studying the behaviour of unicellular eukaryotes, focusing on gliding diatoms (microalgae) and excavates (flagellates).
During my previous postdoc at LadHyX (École polytechnique, Palaiseau) with Gabriel Amselem, I worked on two main projects:
- Erosion of microfluidic channels to homogenise flows;
- Transport of large passive particles by swimming micro-algae.
