Research in physical applied mathematics, motivated by real world problems is central to Dr. Hoeferâ€™s investigations. His research is generally in the field of nonlinear waves with a focus on two areas: 1) fluid or fluidlike dynamics of dispersive media with accompanying wave excitations including dispersive shock waves (DSWs) and solitary waves; 2) dynamics of magnetic media. Methods employed include mathematical modeling, analysis, asymptotics, numerical analysis, and experiment. Dr. Hoefer leads the Dispersive Hydrodynamics Laboratory whose mission is to explore dynamics in novel nonlinear wave, fluidlike systems.
