Research interests

I am interested in the (unusual) mechanics of complex fluids made of living matter ("active fluids"), a research area which lies at the interface between fluid mechanics, soft matter and biology.

Examples of active fluids include suspension of bacteria or the cytoskeleton of living cells. What's common between those is the fact that they are made of self-driven components capable of converting chemical energy into mechanical work. Due to this internal energy conversion, active fluids exhibit macroscopic mechanical behaviours that are unlike those of conventional complex fluids.

A remarkable example is the negative viscosity of bacteria suspensions subjected to shear, a phenomenon first observed experimentally which we explained theoretically (Loisy, Eggers and Liverpool, PRL 2018). Another example is the ability, for a drop of active liquid on a substrate, to propel itself without imparting any mechanical stress locally on the surface: this original mode of self-propulsion that we recently proposed (Loisy, Eggers and Liverpool, submitted) offers an explanation to cell motion in crowded environments.
