Isom Herron

Ph.D. Johns Hopkins University
Applied Mathematics, Hydrodynamic Stability


Professor Herron's research is in one of the richest areas of applied mathematics: the theory of the stability of fluid flows. Common applications are to phenomena in the atmosphere, the oceans, to problems of the motion of ships and aircraft and to internal machinery. Modern approaches involve new techniques in operator theory, energy methods and dynamical systems. Current research interests are in (i) stability of rotating magneto-hydrodynamic flows, (ii) more complicated geophysical flows such as groundwater, for which mathematical models are still being developed.
