People

Tanja works on the structure of text data and multilingual text processing. Her research is driven by the idea that establishing scientific facts about information density in text is a way towards language models that are fairer across languages, more robust and more sustainable.

She holds a PhD in computational linguistics from the University of Geneva. Before joining IDSIA in 2025, she led the Text Group and co-directed the Language and Space Lab at the University of Zurich (2013–2024), and was a visiting scholar at the University of Cambridge and the IT University of Copenhagen.
