I am currently a Postdoctoral Reseracher at the Munich AI and NLP (MaiNLP) lab at the Center for Information and Language Processing (CIS), LMU Munich, led by Prof. Barbara Plank. Before that, I did my Ph.D. at the University of Mannheim, where I was supervised by Prof. Goran Glavaš and advised by Prof. Simone Ponzetto and Dr. Ivan Vulić.

I work at the intersection of natural language processing (NLP) and information retrieval (IR). My research interests are centered around trustworthy AI and information access in resource-constrained environments, where I specifically focus on understanding the behavior of large language models (LLMs) and multilingual retrieval models.
