Research Summary

My research involves the use of molecular simulation and theory to study the behaviour of complex fluids and soft materials, such as liquids, liquid crystals, polymers, or colloids. I have a particular interest studying interfacial and surface phenomena, such as the adsorption of particles at liquid interfaces and the anchoring of liquid crystals at solid substrates.
