Anastasios (Tassos) Roussos was born in Athens in 1983. He received the Diploma degree in Electrical and Computer Engineering from National Technical University of Athens in November 2005. He first joined the CVSP group in the final year of his undergraduate studies (spring 2005) while working on his Diploma Thesis, supervised by Professor Petros Maragos. His Diploma Thesis was in theory and applications of methods based on Partial Differential Equations (PDEs) for denoising, simplification, inpainting and interpolation of general vector-valued images.

Tassos is currently a PhD student in the CVSP Group, school of ECE, NTUA, working in the areas of Image Analysis and Computer Vision. His current research interests include variational and PDE-based methods for enhancement, segmentation, boundary detection and tracking in image data of various types (vector-valued still images, image sequences, 3D image data), with main applications on biomedical image processing.
