Research interests have expanded over the years from initial work in slender body diffraction forces , hydroelastic springing , and wave energy devices to now include nonlinear dynamics , high speed planing , impact hydrodynamics, extreme vessel motions and loads , oscillatory, time dependent real flows , and stern flap hydrodynamics/design . The research involves the application of experimental, theoretical, and numerical methods. The goal of these efforts has been twofold: to define accurate hydrodynamic models which permit the determination of the nonlinear fluid loads and, once having identified the proper hydrodynamic model, solve, both qualitatively and quantitatively, the complicated nonlinear equations of motion. While these research activities have generated a new and better understanding of the physical phenomena involved, they have also provided undergraduate, Masters level, Professional level, and Ph.D. level support in addition to creating opportunities for collaborative faculty efforts.
