## Research
My research interests lie in the area of mechanics and applied
dynamical systems, with emphasis on the behavior of low-order, coupled
nonlinear systems arising from engineering applications.
Almost every engineering system exhibits behavior that is
nonlinear. For many systems the influence of these nonlinearities is
minimal-a linear model is able to satisfactorily describe the dynamical
behavior. However, as the influence of these nonlinearities grows, the
resulting behavior of the system begins to diverge, sometimes
dramatically, from the predictions of the linearized model. Such
differences frequently arise as the forcing on the system increases or
under specific forcing conditions such as occur at resonance. Moreover,
there are certain types of dynamical behavior which can only be
predicted by nonlinear systems. My research interests are focused on
the investigation of the dynamical response of nonlinear engineering
systems. My work has spanned across the areas of vibrations and
dynamical systems, to contact dynamics and control theory, and an
underlying theme to my research is the understanding of these systems
through the development and analysis of simplified models.
