I am a Ph.D. student at the Perceiving Systems department of the Max Planck Institute for Intelligent Systems, supervised by Dimitris Tzionas and Michael J. Black. I am also part of the Max Planck ETH Center for Learning Systems. During the summer of 2022 I was an intern at Meta Reality Labs Research, working with Kaiwen Guo. From June to November 2021 I was an intern at the Mixed Reality & AI Lab in Zurich, working with Federica Bogo and Julien Valentin. Prior to joining PS, I was fortunate to visit and work with Matthias Nießner, at the Visual Computing & Artificial Intelligence. Before going to Germany, I spent 8 wonderful months in Grenoble, working with Philippe Weinzaepfel, Jérome Revaud and Cordelia Schmid, as a member of the Thoth team and NaverLabs Europe. This journey started at the Aristotle University of Thessaloniki , where I studied Electrical and Computer Engineering. |
