Hello World!
I am a tenured Assistant Professor at the Department of Computer Science, University of Nicosia with specialization in Big Data Management and Processing. I am also a Senior Member at the University’s Artificial Intelligence Lab overseeing Data-Intensive Computing initiatives.
As a Researcher, I focus on designing and developing scalable and self-manageable data analysis systems by exploring the intersection between (Big) Data Management, Distributed Systems and Machine Learning. Examples include performance and quality-aware optimization of continuous analytic jobs in edge computing settings, scalable emulation of data-intensive IoT services, benchmarking tools for geo-distributed ML applications, low-cost approximation techniques for self-adaptive monitoring, interoperable analytics over blockchains and federated learning deployments. For the last couple of years, I have also been working on energy- and carbon-aware Data and AIOps, a field that is gaining significant interest due to the need of establishing sustainable practices as part of the Responsible AI movement.
Previously, I was an Adjunct Lecturer and Postdoctoral Fellow at the Department of Computer Science, University of Cyprus. As a Postdoc, I was associated with the Laboratory for Internet Computing. I additionally hold a MSc in Computer Science from the University of Cyprus and a Dipl-Ing in Electrical and Computer Engineering from the National Technical University of Athens. My PhD dissertation targeted developing low-cost probabilistic and adaptive learning models for approximate monitoring in order to improve energy-efficiency and reduce both the volume and velocity of data generated and consumed by IoT services. For the research conducted during my doctoral studies, I was selected by the Heidelberg Laureate Forum as one of the 100 young promising researchers in Computer Science for 2015.
I have extensive experience in European and National co-funded research projects. Currently, I am the Scientific Coordinator for the AdaptoFlow project (Horizon Europe TrialsNet open call) that is in the process of designing a service to support energy-aware AI/ML inference and data stream processing for AI-driven applications deployed in geo-distributed settings including smart cities. Recently, I was the Scientific Coordinator for the AI4IDS project, a nationally funded project that designed an AI-based intrusion detection service as a cloud offering for malware classification and was also the Project Coordinator for the FlockAI project funded by the UNIC SEED grant scheme. FlockAI delivered a framework supporting Machine Learning testing and benchmarking for drone applications. I have also just finished contributing to the EC co-funded ALAMEDA H2020 project where we focused on MLOps for the design of AI-infused services aiding in the data collection of patient daily routine and medical interventions. In the past, I participated as a Work Package Leader to multiple projects (e.g., RAINBOW, Unicorn, PaaSport) funded under the European Commission FP7 and H2020 grant schemes.
Our lab also features a number of other EU and National projects that I help out with. You may see a list here.
