I received my diploma in Computer Science and Engineering from the Computer Science and Engineering Department of the University of Ioannina in 2017. I received my MSc in Computer Science with specialization in software from the Computer Science and Engineering Department of the University of Ioannina in 2020. My research interests include Data Management and Query processing (Efficient Data Indexing and Retrieval on temporal data). I received my PhD from the Computer Science and Engineering Department of the University of Ioannina in 2023, supervised by Prof. Mamoulis and Prof. Bouros. Currently, I am a postdoctoral researcher at TU Delft.

My research centers on advancing scalable, efficient data management systems with a particular emphasis on temporal data, stream processing, and distributed systems. My PhD work focused on innovative indexing solutions for both static interval data and streams of temporal data, addressing the challenges of efficient data indexing and retrieval. In my current postdoctoral research at TU Delft, I am exploring the intersection of distributed systems, transactions, and scalable data management.
