Robert David Deegan is an associate professor of Physics, an associate professor of Mathematics, and an associate professor of Complex Systems. He completed his Ph.D. at the University of Chicago.
Professor Deegan’s research focuses on the dynamics of non-equilibrium systems. As a system, such as a fluid or a solid, is driven from equilibrium, it undergoes a series of transitions to progressively more organized dynamics. Professor Deegan studies dynamical transitions though table-top experiments with the aim of understanding the origin of this behavior in each specific case and in general. His research covers a broad range of phenomena from drying drops to bursting balloons to vibrated slurries. Currently, he is investigating drop impact and the instability that produces the famous Edgerton crown, and pattern formation in chemical reactions and complex fluids.
