Currently a Professor at the Department of Informatics & Telematics, Harokopio University of Athens.
Research interests include algorithms, machine learning, and artificial intelligence.
Academic roots lie in theoretical computer science, with a focus on graph algorithms and matching theory.
Early work centered on efficient algorithms for two-sided matching markets and cycle bases in graphs, combining theoretical insights with practical implementations.
Research has evolved toward machine learning, especially graph-based representation learning methods like Graph Neural Networks (GNNs) for structured prediction.
Also applies image-based and multimodal representation learning to remote sensing and Earth observation.
Maintains a strong interest in the theoretical foundations of AI.
