PhD student

I am working on representation learning methods for multimodal single-cell data, integrating biological pathways and biomedical domain knowledge to improve explainability.

National and Kapodistrian University of Athens

Sep 2022 - Nov 2025

Research Associate - Biomedical Data Scientist

As part of the Plasma Cell Dyscrasias Unit at the Department of Therapeutics, Alexandra General Hospital, our research focused on uncovering the molecular mechanisms and biological processes underlying plasma cell-related hematologic malignancies. My role involved multiomics data analysis, integration, and visualization to derive meaningful insights into disease pathophysiology.

Saphetor

Mar 2022 - Sep 2022

Production Support Bioinformatics Intern

I was working with Saphetor’s data-processing pipeline for next-generation sequencing: VarSome. It is a clinically certified tool for variant discovery, annotation, and interpretation of next-generation DNA sequencing data for whole genomes, exomes, and gene panels, for individual samples, trios, families, and cohorts

Sep 2021 - Mar 2022

Machine Learning Intern

I had the opportunity to work on state-of-the-art ML techniques related to text mining and information retrieval. My learning experience also included: participation in all steps of the publication knowledge graph platform from data collection, data integration and AMP cancer variant guidelines implementation.

Hellenic Centre for Marine Research

Μember of the bioinformatics group: lab42open

Collaboration during my MSc thesis on the topic of Named Entity Recognition of chemical entities in scientific abstracts using neural networks. This project had received funding from the Hellenic Foundation for Research and Innovation (HFRI) and the General Secretariat for Research and Technology (GSRT), under grant agreement No 241 (PREGO project).

Instituto Gulbenkian de Ciencia

Jun 2018 - May 2019

Laboratory Technician

I was working on a project involving bacterial protein expression, protein purification (affinity and ion exchange chromatography) using advanced instrumentation (Akta Purifier) and state of the art chromatographic material and methodologies and I was trained to manually set up crystallization screens, to evaluate crystallization trials and to handle crystals of protein - nucleic acids complexes.
