Background and activities
My roots are in Computer Science and more specifically Computer Graphics but I now venture in other exciting areas also.
I enjoy teaching Visual Computing courses and solving problems in 3D Object Retrieval, Biometrics and the Simulation of the Erosion process on Cultural Heritage objects.
