Personal Profile
Denis Evans was a CSIRO Postdoctoral Fellow at the University of Oxford, a Research Fellow at Cornell University and a Fulbright Fellow at the National Bureau of Standards (USA) during 1979 and 1980. The Commonwealth Scientific and Industrial Research Organisation ( CSIRO) is the national government body for scientific research in Australia. The University of Oxford (informally "Oxford University" or simply "Oxford" located in the city of Oxford, Oxfordshire, England is the The Fulbright Program, including the Fulbright-Hays Program, is a program of grants for international educational exchange for scholars educators graduate Year 1979 ( MCMLXXIX) was a Common year starting on Monday (link displays the 1979 Gregorian calendar) Year 1980 ( MCMLXXX) was a Leap year starting on Tuesday (link displays the 1980 Gregorian calendar) He is a Fellow of the Australian Academy of Science and has won numerous awards, including the Frederick White Prize of the Australian Academy of Sciences (1990), the H. The Australian Academy of Science (AAS was founded in 1954 by a group of distinguished Australians including Australian Fellows of the Royal Society of G. Smith Medal of the RACI (2000). the Boys-Rahman Lectureship of the Royal Society of Chemistry (2000), a Centenary Medal from the Australian Government and the Moyal Medal for distinguished contributions to mathematics, physics or statistics from Macquarie University. The Centenary Medal is an award created by the Australian Government in 2001.

He is also a keen bushwalker and photographer.
Research Interests
Denis Evans heads the Liquid state chemical physics group in the Research School of Chemistry at The Australian National University. The Australian National University, commonly abbreviated to ANU, is a public Research university situated in Canberra, Australia. Denis is best known for the derivation and experimental validation of the Fluctuation theorem, an extension of the Second Law of Thermodynamics. The fluctuation theorem (FT is a theorem from Statistical mechanics dealing with the relative probability that the Entropy of a system which is currently away from The second law of Thermodynamics is an expression of the universal law of increasing Entropy, stating that the entropy of an Isolated system which
Denis Evans has over 280 publications on nonequilibrium statistical mechanics, dynamical systems theory as applied to bulk systems, irreversible thermodynamics, computer simulation algorithms for nonequilibrium systems, the relation of the intermolecular potential function to macroscopic fluid properties and molecular rheology. He has developed nonequilibrium simulation methods including the DOLLS and SLLOD algorithms for the study of shear flow, the Evans’ method for heat flow, the color conductivity method for the determination of self diffusion. Shear flow is- in a solid body the gradient of a Shear stress force through the body in a Fluid, it is the flow induced by such a In thermal physics, heat transfer is the passage of Thermal energy from a hot to a colder body Diffusion is the net movement of particles (typically molecules from an area of high concentration to an area of low concentration by uncoordinated random movement
He is also well known for the development of links between the theory of chaos and properties of fluids including development of the Conjugate Pairing Rule. Chaos (derived from the Ancient Greek, Chaos) typically refers to Unpredictability, and is the antithesis of Cosmos.
