Albane Théry

I am a Simons' Postdoctoral Fellow in the Center for Mathematical Biology at the University of Pennsylvania. I build mathematical and numerical models for hydrodynamics problems that arise in soft active matter and biological physics, with particular interest in self-organization and complex environments.
I completed my PhD in 2022 at Cambridge in the group of Eric Lauga.

Research Interests

I work on problems at the interface between biology and fluid mechanics at small scales. Specifically, I have been working on the influence of confinement on the large-scale patterns that emerge in suspensions of self-propelled particles interacting through the fluid. I also seek to understand the interplay between the properties of complex fluids, and an organism swimming and sensing its surroundings.
Although I carried out experiments for projects in the MMN lab and at McMaster University , my current work is theoretical. That said, some of my favorite projects so far focused on understanding existing experimental data by building minimal models and simulations.
The gallery below shows some snapshot of current and recent research projects.

Collective dynamics of Magnetotactic bacteria

Plumes emerge and grow in a concentrated suspension of MTBs aligned to an external field. We explain these novel dynamics using hydrodynamic singularities.

Confinement of microswimmers

We study the instabilities that arise in a confined suspensions of swimmers that align respond to external cues.

Stability of squirmer clusters

How much do hydrodynamic interactions control the stability clusters of self-propelled droplets? We study the hydrodynamic formation and breaking of circles of squirmers

Efficiency of helical swimming in suspensions.

We show how hydrodynamic interactions with surrounding particles improves the efficiency of helical propulsion, as shown experimentally.

Trapping in foams

Study of the spatial distribution of Chlamydomonas algae in a microfluidic chamber mimicking foam Plateau borders. A geometric billiard model shows that the swimmers get trapped in corners.
