Denis James Evans, (born April 19, 1951 in Sydney, Australia), is a Professor in the Research School of Chemistry at the Australian National University. He is widely recognised for his contributions to nonequilibrium thermodynamics and nonequilibrium statistical mechanics and the simulation of nonequilibrium fluids.

He is also a keen bushwalker and photographer.

Denis Evans heads the Liquid state chemical physics group in the Research School of Chemistry at The Australian National University. Denis is best known for the derivation and experimental validation of the Fluctuation theorem, an extension of the Second Law of Thermodynamics.

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.

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.
