Since the Summer of 2004, I am with the Dept. of Computing @ Goldsmiths College, University of London, UK From 1998 until 2004 I was with Brown University Division of Engineering, Box D LEMS - Lab. for Eng. huMan/Machine Systems Providence, RI 02912, USA Cell: +1.401.743.0531 |

The main scientific theme of my work is based on the following

The following are more practical and immediate concerns.
How can we deal with the ever growing amount of 3D hypermedia data that shall immerse us in the Virtual World of tomorrow? Useful 3D shape representation(s) and elicitation process(es) are needed. The DBMS (Data Base Management Systems) of the (near) future will require tools for authoring, retrieving, updating, comparing, analyzing, such data, in particular for FIS (Financial Information Systems), GIS (Geo-matics/graphic Info. Sys.), MIS (Medical Info. Sys.), Architectural and Archaeological modeling and Virtual and Augmented Reality applications.
My collaboration with the Vision team at Brown is centered on the definition, implementation and application of such a 3D shape representation, through the design of a useful shape elicitation process, namely 3D shocks "a la Kimia".
My collaboration with the Graphics team at Brown focused on mixed initiatives for gestured-based interactions with a sketching system. The latter permits the user to manipulate images to retrieve viewing geometry and reconstruct a 3D scene, even when only a single view is available. This can be applied to photographs, video imagery or even drawings and paintings.
My collaboration with the Archaeology & Anthropology team at Brown aims at providing specialists new digital tools to represent, manipulate and document large object databases made to be built from complex fragmented and eroded shapes of artefacts found on site, in particular for the Great Temple of Petra, Jordan.
My collaboration with the Object Representation team at the Institute for Computer Vision and Graphics, of the Technical University of Graz, aimed at improving existing digital tools to reconstruct, document and managed large object databases of entire cities and interiors of large buildings, projects called CyberCity & CyberMonument.
I am also looking at applying wave propagation modelling and simulation through cellular automata for image rendering, visibility computations, crack propagation, financial and market data analysis, ..., and other phenomena.
