I am a final year PhD Student at the University of Pennsylvania, working on computer vision with my advisor, Kostas Daniilidis. Before that, I did my undergraduate studies at the National Technical University of Athens, where I worked with Petros Maragos. I have spent time at Max Planck Institute working with Michael Black and at Facebook Reality Labs working with Yaser Sheikh and Tomas Simon.
