My research topics are centered on the theoretical study of fluid properties in the presence of various objects such as colloids or polymers at the interface. Theses studies could have applications in biophysics, for the shaping of materials, for the transport of particles or for sorting objects by size.

Trapping energy of a spherical particle on a curved liquid interface. ( PDF Version HAL )
Journal of colloid and interface science 2013;405():249-55.
We derive the trapping energy of a colloidal particle at a liquid interface with contact angle θ and principal curvatures c1 and c2. The boundary conditions at the particle surface are significantly simplified by introducing the shift ε of its vertical position. We discuss the undulating contact line and the curvature-induced lateral forces for a single particle and a pair of nearby particles. The single-particle trapping energy is found to decrease with the square of both the total curvature c1+c2 and the anisotropy c1-c2. In the case of non-uniform curvatures, the resulting lateral force pushes particles toward more strongly curved regions.
