About

Theo is a Professor at the Department of Computer Science (IDI), NTNU Trondheim. He is part of the Visual Computing group within the Computing unit.

His current research areas include 3D Object Retrieval, Biometrics and other problems in the area of shape analysis. Previous research experience also includes facial data processing, shape segmentation, shape registration and shape problems in cultural heritage.

Relatively recently, Theo coordinated the PRESIOUS EU project that applied visual computing techniques to cultural heritage problems and participated in the D4FLY EU project that developed on-the-move biometric technologies for the verification of traveler’s identities and in the CHANGE ITN EU project (15 PhD theses) that applied visual computing techniques for the monitoring and measuring of change on cultural heritage artifacts.

His first degree is in Computer Science, his Masters in Computation and his DPhil in computer graphics and parallel processing, all from the 1980's.
