講座人簡介：Professor Roger Horn graduated with BSc (Hons) in physics from Monash University (Australia) followed by a PhD on the physics of liquid crystals from Cambridge University (1977). After a post-doctoral fellowship at the Université de Paris Sud, he joined the Australian National University in 1978 where he worked with Jacob Israelachvili on pioneering surface force measurements. In 1988 he moved to the US National Institute of Standards and Technology in Gaithersburg, Maryland, before returning to Australia and joining the University of South Australia in 1992. Roger was Deputy Director of the Ian Wark Research Institute from the time of its foundation in 1994 until mid-2009. He is now the Dean of Research Training at Deakin University in Melbourne, where he has oversight of research students across the university. His research has included measurements of surface forces and adhesion between particles suspended in liquids; the properties of very thin liquid films; liquid crystals; biophysics; and static electricity. He is respected internationally for his innovative experimental work in these areas, with his 75 research publications having attracted over 6000 citations.
