Bio

I am a postdoctoral researcher at the Health NLP Lab headed by Carsten Eickhoff in the University of Tübingen. My research is supported by the AI & Data Science Fellowship Program at the university. I completed my PhD from Max Planck Institute for Informatics, Saarland University, under the supervision of Simon Razniewski and Gerhard Weikum.

My primary research areas are Generative AI, Natural Language Processing and Information Retrieval. My overarching goal is to develop systems that can extract, organize and reason with knowledge on the Web while maintaining transparency and accountability to the end user. In my recent works I developed methods to efficiently aggregate count information from Web data.
