Hello! My name is Andria Trigeorgi and I am a Postdoctoral Researcher at Algolysis Ltd, where I coordinate the research project ATLAS on scalable atomic distributed shared memory. My research focuses on distributed storage systems: designing, implementing, and experimentally evaluating strongly consistent and fault-tolerant distributed algorithms.
I hold a PhD in Computer Science (2020–2025) from the University of Cyprus, where I conducted my doctoral research under the supervision of Prof. Chryssis Georgiou and Dr. Nicolas Nicolaou, focusing on a dynamic Distributed Storage System (DSS) for highly concurrent and strongly consistent file sharing. I also hold an MSc in Computer Science (2016–2018) and a BSc in Computer Science (2012–2016) from the University of Cyprus.
