About Me

Hey there! I am Stamatios Georgoulis, although most people know me as 'Stam', and I come from a small but beautiful island in the Aegean Sea, called Sifnos. Currently, I am a 3rd-year post-doctoral researcher at the CVL group of ETH Zurich, working with Prof. Luc Van Gool and Dr. Dengxin Dai on the R&D project "TRACE: Toyota Research on Automated Cars in Europe". I am fascinated by many research topics, by you will usually find me publishing image generation, dense prediction, and multi-task learning papers.

Before coming to Zurich, I was a doctoral student at the PSI-VISICS group of KU Leuven. There, I received my PhD under the supervision of Prof. Luc Van Gool and Prof. Tinne Tuytelaars, and I also had the pleasure to collaborate with Prof. Mario Fritz, Prof. Tobias Ritschel and Dr. Konstantinos Rematas. During my PhD, my research was mainly focused on extracting surface characteristics and lighting - in particular, 3D shape, surface reflectance, and environmental illumination - from images.

Further back, before even arriving in Leuven, I received my diploma in Electrical and Computer Engineering from the Aristotle University of Thessaloniki. I conducted the research for my diploma thesis on "Adaptive Pain Detection via Webcam using Advanced Image Processing Techniques" in collaboration with Dr. Stefanos Eleftheriadis under the supervision of Prof. Leontios Hadjileontiadis. During my stay in Thessaloniki, I worked as a student research assistant in the Signal Processing and Biomedical Technology Unit.
