The Benjamin Levich Institute for Physico-Chemical Hydrodynamics is a research institute located on the campus of the City College of New York (CCNY), the flagship school of the City University of New York. The Institute is comprised of five faculty from CCNY – Jeff Morris (director) and Charles Maldarelli (both from Chemical Engineering) and Joel Koplik, Mark Shattuck, and Hernan Makse (all from the Physics Department), and associated graduate and postdoctoral students. The faculty work co-operatively on interdisciplinary problems in soft mater physics, including fluid and granular mechanics, molecular dynamics simulations, interfacial science and network and data science theory.

Current research interests focus on friction in flows of dense suspensions of  particles, the microrheology of complex fluids,  self-propelled (active ) colloidal engines, the dynamics and self-assembly of colloids  at fluid interfaces, microfluidics in lab on a chip devices, static and  dynamic transitions  of jammed states of non-spherical and deformable particles,  jamming dynamics in sediment transport,  neural networks of the brain and the spread of information over social networks.
