I am a machine learning scientist, a postdoctoral fellow at the Archimedes AI unit and the University of Athens and an adjunct lecturer at NCSR Demokritos and the University of Athens. Additionally, I am a founding member of Visible Machiines, an Athens-based non-profit organisation that researches and informs on the social dimensions of Artificial Intelligence. I obtained my PhD in computer science from Imperial College London, and my MEng in electrical and computer engineering from the National Technical University of Athens. Previously, I spent time at Google Deepmind, École Polytechnique Fédérale de Lausanne , KU Leuven, NCSR Demokritos and Universitat Politècnica de Catalunya. I conduct basic and applied research on several machine learning topics, particularly within Geometric/Graph Deep Learning, where I design and theoretically analyse data-driven methodologies for geometric and symmetric data, such as complex networks, physical systems, 3D objects and weight spaces. Additionally, I studiy AI from a sociotechnical angle, with a particular focus on algorithmic auditing and AI interpretability. My work has been published in leading conferences (NeurIPS, ICML, CVPR, ICCV, ECCV) and journals (TPAMI), while I regularly engage in educational activities and academic service.
