I am a posdoctoral researcher in Natural Language Processing from Knowledge Technology Research Group active at FIT-BUT in Brno, Czech Republic. My faculty webpage is available here.
My main research interests are problems related to Large Language Models, Information Retrieval, Question Answering and Fact-Checking. This includes topics such as latent variable models, document retrieval/re-ranking, machine comprehension, cross-lingual continued pretraining or methods for faithful explainability.
If you are a student looking for BSc/MSc thesis supervision in Natural Language Processing and you are not afraid of doing the challenging research, feel free to contact me.
