Dr. Preslav Nakov is Professor and Department Chair at the Natural Language Processing department of Mohamed bin Zayed University of Artificial Intelligence (MBZUAI). His research interests include computational linguistics and natural language processing, large language models, hallucinations, fact-checking, disinformation, propaganda, fake news, media bias, and machine-generated text detection. He is part of the core team at MBZUAI's Institute for Foundation Models that developed Jais, the world's best open-source Arabic-centric LLM, Nanda, the world's best Hindi model, and LLM360, the first truly open LLM. Preslav Nakov received a PhD degree in Computer Science from the University of California at Berkeley (in 2007, supported by a Fulbright scholarship and a UC Berkeley graduate fellowship), and a diploma (BSc+MSc) from the Sofia University.
