My main research interest is surface reconstruction. It is one of the significant applications of scattered data interpolation and approximation. In practice, it is very much related to the subject of computational geometry and object modelling where curve, surface, solid or object representation is to be sought from a given finite set of data. The obtained mathematical representation is often studied and the reconstructed object is placed in computer graphics environment for viewing, printing, or further manipulation. Besides, I am also interested in computational algorithms particularly in shortest path problem. Real road networks in transportation and industrial automation and motion planning in robotics are amongst the applications of shortest path problem.
