Ran Holtzman

Ran is an Associate Professor (Reader) in Coventry University and the leader of the Engineering Applications of Fluid Mechanics group, within the Fluid and Complex Systems Research Center. He seeks fundamental understanding of environmental and energy applications in which multiphase and reactive subsurface flow is key. Of particular interest is the pore-scale origins of nonequilibrium—emergence of unstable, preferential pathways, hysteresis and rate-dependency, and their interplay with hydrodynamics, phase transitions and matrix alteration due to bio-chemo-mechanical processes such as fracturing and dissolution. His research cuts across the interface of earth sciences, engineering and physics, combining experiments, numerics and theory.

Ran received his PhD from UC Berkeley, working with Tad Patzek on micromechanics of granular materials. He was a postdoctoral associate at MIT with Ruben Juanes, studying multiphase flow in deformable porous media. Prior to joining Coventry, he was a faculty in the Hebrew University of Jerusalem, Israel, and a visiting scholar in the Institute of Environmental Assessment and Water Research (IDAEA-CSIC) in Barcelona, Spain.
