Research
Research in brief:
Nonlinear evolution partial differential equations. In particular, the study of front propagation phenomena in equations of pseudo-parabolic, kinetic,
parabolic and hyperbolic type. This amounts to study travelling waves and rarefaction waves, moving interfaces and fronts invading unstable states.
Some of my research on the above topics was motivated by physical problems arising in infiltration in porous media. Most recently,
I have looked at some fluid dynamic problems related to this issue from a more applied, although still mathematical, point of view. This includes
modelling and rigorous mathematical analysis of accumulation in thin-film viscous flows over a smooth substrate in a limit in which both gravity
and surface tension balance. Currently, I am also interested in understanding some processes of two-phase flow by stochastic analysis of simple models of
a two dimensional porous medium.
