I am an Assistant Professor in the Computer Science Department at the IT University of Copenhagen (ITU). My research focuses on developing data management tools that improve the efficiency of modern data analytics and data science workloads, with an emphasis on spatial workloads.

Before joining ITU, I was a postdoctoral researcher at the Technical University of Berlin (TUB) and a junior fellow at the Berlin Institute for the Foundations of Learning and Data (BIFOLD). I earned my PhD from École Polytechnique Fédérale de Lausanne (EPFL) in 2019, where I was advised by Prof. Anastasia Ailamaki. During my doctoral studies, I also spent four months as a visiting researcher at New York University (NYU) with Prof. Juliana Freire. My dissertation research focused on query processing for spatial and temporal data exploration. I obtained a Diploma M. Eng. Degree in Electrical and Computer Engineering from the National Technical University of Athens (NTUA) in 2013.

I am the recepient of a VLDB 2022 Distinguished Reviewer Award and a SIGMOD 2018 Best Demonstration Award. I serve as Diversity and Inclusion co-chair for EDBT 2025-2026, and as Proceedings co-chair for SIGMOD 2025.
