"How deep is your love? Like the ocean?" Looking out at the Balearic Sea got me thinking about ancient feelings. Just how deep *did* the Romans and Greeks love? Come find out at the first poster session of @LREC2026! 📍 Poster 1196 🕐 11:20 - 13:00

A photo of me smiling broadly at the camera. I am standing on a sandy beach, and right behind me are the beautiful blue waves of the Balearic Sea stretching out to the horizon under a bright, sunny sky.

I am honored to receive the 2025 #GSCL Best Thesis Award at #KONVENS in Hildesheim for my Master’s thesis, which investigates multilinguality and develops language models for Ancient Greek and Latin. Thank you to my mentors and collaborators. I look forward to what comes next.

How and when do multilingual LMs achieve cross-lingual generalization during pre-training? And why do later, supposedly more advanced checkpoints, lose some language identification abilities in the process? Our #ACL2025 paper investigates.

Probing classifier performance comparison between early and late checkpoint across layers. While the early checkpoint shows uniformly high performance, the later checkpoint exhibits relatively high variance across layers.

What did Aristotle actually write? We think we know, but reality is messy. As ancient Greek texts traveled through 2,500 years of history, they were copied and recopied countless times, accumulating subtle errors with each generation. Our new #NAACL2025 paper tackles this fascinating challenge.

Debates aren’t always black and white—opposing sides often share common ground. These partial agreements are key for meaningful compromises Presenting “Perspectivized Stance Vectors” (PSVs) — an interpretable method to identify nuanced (dis)agreements 📜 arxiv.org/abs/2502.09644 🧵 More details below
