Khalid Al-Khatib is an Assistant Professor in Natural Language Processing at the University of Groningen. His main research interests are computational argumentation, bias detection, and discourse analysis. In his PhD thesis about argumentation strategies, Khalid investigates questions such as: How do people argue on the Web? What are the strategies that people use to persuade others? Which strategies are the most successful ones in particular contexts? Khalid published several argumentation-related papers on top-tier venues including AAAI, ACL, EMNLP, etc. and also serves on the respective program committees. He has been contributing to the development of the argument search engine 'args.me'. Khalid is one of the recipients of the IBM PhD Fellowship Award (2017).
