I did my BSc in Artificial Intelligence and Data Science at FCUP/FEUP, University of Porto, and I am now finishing an MSc in Data Science.

The two halves suit each other. The degree gave me the AI side, how models are built and what happens inside them, and the master's gave me the data side, statistics, experimental design and the discipline of producing a result you can actually defend. I have ended up working at the seam between them, on whether a model's output can be explained and trusted rather than only measured.

That is what my MSc thesis is about: interpretability of large language models. I build tools that show what a Transformer attends to, and use those signals to detect and audit social bias in BERT and GPT-2.

Outside the thesis I build machine learning systems end to end, from messy data to something a person can actually open and use. I have worked on computer vision, robotics, audio, retrieval-augmented generation, reinforcement learning, tabular prediction, multi-agent systems and a fair number of web and desktop apps. The common thread is curiosity about why a model does what it does.

My Research Interests:

• Interpretability and mechanistic analysis of Transformers
• Explainable AI (XAI)
• Bias detection and fairness auditing in language models
• Faithfulness evaluation of explanations
• Human-in-the-loop and human/AI auditing workflows

I am open to:

• any collaboration work,
• machine learning projects (development or research),
• research internships and junior positions, and
• writing or reviewing on interpretability, XAI and evaluation.
