Penn Complex Fluids Lab

Principal Investigator: Paulo E. Arratia

Everything flows. From water and air to ice to grains to rock, flow creates the complex structures and landscapes in which we live. The Penn Complex Fluids Lab sits at the intersection of fluid dynamics, soft & living matter, and environmental science. We seek to develop fundamental understanding of the physical/chemical properties that govern the structure and behavior of naturally occurring complex fluids. By advancing this understanding, we seek to inspire the design of sustainable materials with unique properties.
