  Research Interests

My research focusses on theoretical soft matter physics and hydrodynamics at interfaces. I am particularly interested in the dynamics of thin viscous films, the physics of wetting and adhesion, surface waves, liquid crystals on curved surfaces, and multiphase flows in porous media.
