Biography

Professor Ray Dagastine leads a research group in interfacial phenomena focused on the interactions between drops, bubbles and particles that control soft matter in the Dept of Chemical and Biomolecular Engineering in the Melbourne School of Engineering.
During his appointment of the University of Melbourne Professor Dagastine has been an ARC Future Fellow (2010 - 2014) and a Senior Technology Fellow at the Melbourne Centre of Nanofabrication (2012 - 2015).
Dagastine is also the initiative chair of the Materials Research Hallmark Initiative at the University of Melbourne and is the academic leader of a the Materials Characterisation and Fabrication Platform .
His research interests are in the area of particulate and droplet interfacial phenomena, emulsion stability and deformable surfaces. He 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. 

He also has research interests in structure in complex fluids, non-equilibrium surface forces, and protein interactions and nanomechanical properties of capsules and micro-particles.
