Jessica Liley: Jessica completed her MSci in Chemistry at Bristol University, with a year in Industry working for Unilever Research. Her DPhil, also in collaboration with Unilever, is exploring the surface and solution behaviour of biosurfactant/conventional surfactant mixtures using neutron reflectivity and small angle scattering. The work also involves a large amount of synthesis of deuterated biosurfactants and the separation of these via chromatographic methods. When she isn’t investigating the air/water interface, she likes to swim, row and surf on it instead.
