Hello! I am a Research Scientist at Google DeepMind, working on 3D computer vision. Previously, I obtained my PhD at the Computer Vision Lab of ETH Zürich, where I worked with Prof. Luc Van Gool and Dr. Jordi Pont-Tuset on 2D scene understanding. I received my M.Eng degree from National Technical University of Athens, School of Electrical and Computer Engineering. I was a member of the CVSP lab working on human action recognition in videos with Prof. Petros Maragos. I have interned in Facebook AI Research (FAIR), where I worked on multi-task learning with Prof. Iasonas Kokkinos. This personal web-page will be updated with my research work.
