Research and Professional Interests

Research Statment

Currently I am working on my PhD thesis. I am aiming to generate a spatial model of human anatomy by using machine learning techniques on a large data set of 3D CT scans. The ultimate goal is to fuse this spatial model with formal ontologies from the area of Semantic Web.
