Vasiliki Vasileiou

Hi! I am a PhD Candidate at the National Technical University of Athens and a PhD Fellow at the Archimedes Research Unit of Athena Research Center, advised by Prof. Kostas Daniilidis and Prof. Petros Maragos. My research interests lie in Computer Vision and Machine Learning, with a particular focus on geometric computer vision, 3D understanding, neural rendering, and language-guided visual learning. I have also been a Visiting Associate at the GRASP Lab at the University of Pennsylvania.

Before starting my PhD, I completed my MSc in Artificial Intelligence at the University of Amsterdam, where my thesis on language-driven 3D scene understanding was supervised by Prof. Martin R. Oswald and Dr. Silvan Weder. Prior to that, I completed my undergraduate studies in Electrical and Computer Engineering at the National Technical University of Athens, where I was supervised by Prof. Petros Maragos during my thesis.
