"For outstanding contributions that elucidate the microscopic basis of the flow properties of suspensions, and their influence on macroscopic flow phenomena."Background:
Jeff Morris is the Director of the Levich Institute (since 2015) and Professor of Chemical Engineering at CUNY City College of New York. Morris is co-director of a FERMAT Foundation research program in Toulouse, France. He received his bachelor’s degree at Georgia Tech (1989), and his MS (1991) and Ph.D. (1995) at Caltech (1995).
Morris develops constitutive and bulk fluid mechanical descriptions appropriate for complex fluids, based in the fundamental understanding of the microstructure. Defining questions are: How are mixture flows intrinsically different from their single-phase counterparts, and why? What is the appropriate predictive framework for these materials accounting for their multiphase nature? The focus has been on suspensions, from submicron colloids to sand slurries. Unifying features of these materials are the influence of hydrodynamic interactions and the flow-induced microstructure on rheology and bulk flow. Morris has analyzed two distinct forms of particle migration, one induced by the bulk rheological influence of the particles and known as shear-induced migration, and one driven by inertia. Morris has recently focused on frictional interactions between particles in viscous liquids, toward an understanding of shear thickening. Morris is an APS Fellow (since 2013) and was awarded the 2015 J. Rheology Publication Award, as well as the 2017 AICHE/Shell Thomas Baron Award for Fluid-Particle Systems. Jeff Morris is an Associate Editor of the Journal of Fluid Mechanics and authored the text A Physical Introduction to Suspension Dynamics, with Elisabeth Guazzelli.
