- Research Methods
The main topic of my research is the study of
nonlinear wave phenomena, especially with applications in water waves.
I use analytical techniques ranging from soliton theory and partial
differential equations to dynamical systems, perturbation theory and
Riemann surfaces. The computational methods I use cover a wide range
as well, from symbolic computation to continuation methods, data
analysis and spectral methods.
