Research summary

  • Applied dynamical systems

    . Understanding complicated dynamics (e.g. chaos) in physical systems governed by ordinary or partial differential equations in terms of bifurcation theory. Global bifurcations (homoclinic and heteroclinic orbits). Bifurcations (grazing and sliding) unique to piecewise-smooth systems. Parametric resonance; the `Indian Rope trick'. Application across engineering to aircraft and structural dynamics, power electronics, fluid-structure interaction.

  • Numerical bifurcation theory

    . Path-following; use of the codes AUTO and CONTENT. Numerical analysis of homoclinic and heteroclinic bifurcations, including homoclinic orbits to periodic orbits, numerical branch-switching and stability calculations. Algorithms for periodic orbits of large systems.

  • Localised phenomena

    . Existence theories for multiplicities of homoclinic ...
