- New paper : "Hydrodynamically-bound states of a pair of microrollers: a dynamical system insight" accepted in Physical Review Fluids, https://arxiv.org/abs/1811.05168. In this paper I show that hydrodynamic bound states can emerge in systems of microrollers due to the competition between gravity and torque-induced flow fields. These states undergo a cascade of bifurcations and are reminiscent of the stable colloidal creatures observed in microroller suspensions.

- New paper: "Simulations of Brownian tracer transport in squirmer suspensions" with Eric Keaveny, Franck Plouraboué and Eric Climent. We combine the Fluctuating Force Coupling Method with the squimer model and our new time integration scheme for the overdamped Langevin equations to study the transport of colloidal particles in active suspensions. We compare our results to experiments and quantify the contribution of hydrodynamic interactions, Brownian motion and collisions on particles' displacement.
