About me
My name is Kathy; I am a third-year PhD student in Computational Linguistics at CIS. I'm co-supervised by Alex Fraser and Jindřich Libovický (Charles University, Prague).
My research interests are multilingual language models, cross-lingual transfer, and how they function.
I'm affiliated with and supported by the Munich Center for Machine Learning.
Between autumn 2018 and spring 2021, I obtained my Master's degree from CIS. Before that, I studied English Philology and Computer Science.
I am currently on a research visit to Prague!
