Jeff Morris is the Director of the Levich Institute (since 2015) and Professor of Chemical
Engineering at CUNY City College of New York (CCNY), and previously served as the Chair of the CCNY Department of Chemical Engineering from 2013 to 2016. He received his bachelor’s degree at Georgia Tech (1989), and his MS (1991) and Ph.D. (1995) at Caltech. He has worked industrially for Shell Research Amsterdam (1994-1995) and Halliburton Energy Services (2002-2004).
Morris develops constitutive and bulk fluid mechanical descriptions appropriate for complex fluids. 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, as well as particle migration. Morris has recently focused on instabilities due to inertia in flows of suspensions and on frictional interactions between particles in viscous liquids, toward understanding of shear thickening.
Morris was elected Fellow of the American Physical Society (APS) in 2013 and of the Society of Rheology in 2019. He was awarded the 2015 and 2020 J. Rheology Publication Awards, the 2017 AICHE/Shell Thomas Baron Award for Fluid-Particle Systems, the 2019 Stanley Corrsin Award of the APS.
Jeff Morris served as the Secretary-Treasurer of APS Division of Fluid Dynamics (2018-2021), and is an Associate Editor of the Journal of Fluid Mechanics. He authored the text A Physical Introduction to Suspension Dynamics
