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

I am usually at ATHENA RC, doing research on Explainable AI under the supervision of Christos Diou, Theodore Dalamagas, and Eirini Ntoutsi. I also collaborate on explainability research with colleagues in Munich, including Giuseppe Casalicchio and the entire IML team led by Bernd Bischl. I keep an ongoing interest in probabilistic ML, especially likelihood-free inference, where I often work with Michael Gutmann.


I actively contribute (and sometimes lead) open-source projects like Effector and ELFI.


I have served as a reviewer for conferences like NeurIPS, AISTATS, 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 need no more 500-pound websites.


I sometimes work on interpretability projects in industry, like LLM explainability for novelcore (6-month project at 2023).

Research Visit @ LMU
2025 (January - March)
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.
