PhD in Explainable AI @ DIT/HUA
Research Assistant @ ATHENA RC
Working on interpretable machine learning systems

I work at ATHENA RC and do my PhD at HUA supervised by Christos Diou. My research is on interpretable ML systems, with two main strands: eXplainable AI, which explains black-box models [1][2] or builds x-by-design models from scratch [3], and Simulation-based Inference, which fits interpretable scientific simulators to data [4].


On SBI, and in probabilistic ML in general, I often work with Michael Gutmann.


On XAI, I often work with Giuseppe Casalicchio and the IML team led by Bernd Bischl.


I contribute to, and sometimes lead, open-source projects like Effector and ELFI.


I publish at and review for conferences like NeurIPS, AISTATS and ECML, and journals like JAI.


I believe in slow science. The current pace burns people out and buries meaningful research under an avalanche of noise.


Personal websites are great, but we don’t need more 500-pound websites.

Research Visit @ LMU
2025 (January - March), 2026 (June - July)
I mainly developed Effector, an eXplainable AI package for tabular data. I worked with some people from the IML group, including Hubert Baniecki, Julia Herbinger and Giuseppe Casalicchio.

PhD in Explainable AI @ DIT-HUA
2023 - Present
Supervised by Prof. Christos Diou, Prof. Eirini Ntoutsi, and Theodore Dalamagas.
Researching explainable-by-design models and post-hoc techniques for black-box models, with a special focus on explaining deep learning systems trained on tabular data.

MSc in Data Science @ UoE
2019 - 2020
MSc at the University of Edinburgh, working with Michael Gutmann on likelihood-free inference.
There, I took two pivotal courses, MLPR (Ian Murray) and PMR (Michael Gutmann), that shaped my understanding of machine learning.

Diploma in Electrical and Computer Engineering @ ECE AUTH
2011 - 2017
5-year Diploma from Aristotle University of Thessaloniki. This is where I got into machine learning, working with Anastasios Delopoulos on Stereo Vision using Deep Neural Networks.
