About Me


Hi! I am a first-year PhD student at Saarland University, advised by Alexander Koller. Prior to that, I worked at the MaiNLP Research Lab at LMU Munich under Barbara Plank, mainly focusing on Information Retrieval and model evaluation. Furthermore, I hold a BSc in Computer Science from the University of Würzburg, and an MSc in Computer Science from Trinity College Dublin.

My research interests focus on out-of-distribution generalisation of language models, specifically compositional generalisation and length generalisation. For instance, I am currently exploring how interactive learning setups (e.g., teacher-student frameworks or interactive environments) can shape the data distribution of tasks to enable better compositional generalisation. I am also quite excited about research involving multimodal grounding of language models, though I do not currently work on such topics actively.

If you are interested in collaborating on research projects or chatting in general, please feel free to reach out!
