About me
I am a language AI researcher based in Lausanne. I completed my PhD in Computer Science at the University of A Coruña in June 2026, and was a Visiting Researcher at LMU Munich and EPFL.
My research focused on efficient, robust, and interpretable language models, especially in multilingual, low-resource, and non-standard language settings.
I am looking for industry roles in Switzerland or remote. Available immediately; EU citizen.

Reading Cross-Lingual Semantic Differences from Apertus
Scores each word of parallel Swiss government web pages (English vs. German, French, and Italian) for how much its meaning differs from the other version, using Apertus 8B as a frozen reader. Middle-layer hidden-state alignment and contrastive surprisal, combined by a logistic regression head, reach 37.4 Spearman on the held-out test, vs. 17.1 for the best released baseline.
