The research interests of Raymond Dagastine are in the area of particulate and droplet interfacial phenomena, emulsion stability and deformable surfaces. Raymond is a leading researcher in developing experimental methods and theoretical analytical tools to study interaction forces between deformable liquid-liquid interfaces using both optical techniques and atomic force microscopy.

Raymond also has research interests in structure in complex fluids, non-equilibrium surface forces, and protein interactions and nanomechanical properties of living cellular systems. Raymond is a member of the Particulate Fluids Processing Special Research Centre.
