Molecular Simulation of Fluids

Richard J. Sadus is a professor at Swinburne University of Technology, where he has held leadership positions as acting dean, department chair and centre director. His research has also been conducted at the universities of Karlsruhe and Cologne under the auspices of the Alexander von Humboldt Foundation and he was previously a visiting researcher at the University of California, Berkeley. A focus of current research is the development of molecular simulation methods to directly predict thermodynamic properties and phase behaviour from the underlying inter-particle interactions. This involves using object-oriented techniques and parallel programming on high performance computing environments. Professor Sadus is the author of an earlier research monograph: “High Pressure Phase Behaviour of Multicomponent Fluid Mixtures,” which is also published by Elsevier. He is a Fellow of the American Institute of Chemical Engineers.
