I started to work as a doctoral researcher at the Educational Technologies group, DIPF, in 2025. Before that, I worked as a research intern at UKP TU-Darmstadt and obtained a master's degree in Speech and Language Processing at the University of Edinburgh, where I investigated the inverse scaling behaviour of large language models under multilingual settings. Outside of researching, I enjoy hiking and learning languages.
