Biography

I am working on mathematical modeling and numerical simulation of homogeneous-heterogeneous, nonlinear and coupled phenomena and the subsurface flow and transport of contaminants (unsaturated-unsaturated zone, unbalanced transport, density-dependent phenomena). I am also interested in watershed hydrology (surface and underground processes) and remote sensing (soil moisture and other soil surface / atmospheric conditions variables) as well as geosciences applications from information technology to environmental modeling.
