I am a Postdoctoral Researcher of Computer Science at the Technical University of Berlin (TUB), working with Prof. Volker Markl at the Database Systems and Information Management (DIMA) group. I am currently conducting research on spatial big data analytics and I am further interested in robust stream processing in IoT environments.

I received my PhD from the École Polytechnique Fédérale de Lausanne (EPFL) in 2019, where I worked in the Data-Intensive Applications and Systems (DIAS) lab on query processing algorithms and indexing methods for spatial and temporal data exploration with Prof. Anastasia Ailamaki. In summer 2016, I was a visiting researcher at the New York University (NYU), where I worked with Prof. Juliana Freire.

I received the Diploma M. Eng. Degree in Electrical and Computer Engineering from the National Technical University of Athens in 2013.

I gave a talk on "AgoraEO" at the Geo-Information Processing Department of the University of Twente, Netherlands. Here you can watch a recording of the talk.
Happy to participate in the round table session on Spatio-temporal Data System at VLDB 2021.
Very honored to be selected as a BIFOLD Junior Fellow!
I serve as a Reviewer for the VLDB Journal and the Knowledge and Information Systems (KAIS) Journal.
New paper "Monitoring of Stream Processing Engines Beyond the Cloud: an Overview" accepted at VLIoT 2021.
A medium post on our recent work that proposes using distance-bounded spatial approximations to exploit modern hardware and accelerate spatial queries.
New paper "Agora-EO: A Unified Ecosystem for Earth Observation -- A Vision For Boosting EO Data Literacy --" accepted at BiDS 2021.
I serve as PC Member of VLDB 2022, EDBT 2022, and AIMLSystems 2021.
New paper "GeoBlocks: A Query-Cache Accelerated Data Structure for Spatial Aggregation over Polygons" accepted at EDBT 2021.
New paper "Towards Resilient Data Management for the Internet of Moving Things" accepted at BTW 2021. Here you can watch a recording of the talk.
New paper "The Case for Distance-Bounded Spatial Approximations" accepted at CIDR 2021. Here you can watch a recording of the talk.
I am co-chairing the BOSS 2020 Workshop (co-located with VLDB). Check out our website for videos, slides, and further material on cool open source systems.
