I always worked in the area of numerical modeling, first investigating quantum effects in semiconductors, then simulating nonlinear self-organization phenomena in solid-state materials, and finally in signal and image processing. My current interests are the 3D reconstruction of underwater scenes, taking into account refractive effects, and benthic habitat classification based on conventional and multispectral imagery.
