Dan Roth is a Professor in the Department of Computer Science at the University of Illinois at Urbana-Champaign and the Beckman Institute of Advanced Science and Technology (UIUC) and a Willett Faculty Scholar of the College of Engineering. Prof. Roth got his B.A Summa cum laude in Mathematics from the Technion, Israel, in 1982 and his Ph.D in Computer Science from Harvard University in 1995. Prof. Roth has published broadly in machine learning, natural language processing, knowledge representation and reasoning. His paper awards include the best paper award in the International Joint Conference on Artificial Intelligence (IJCAI) in 1999 and the American Association of Artificial Intelligence (AAAI) Innovative Applications of AI Award in 2001. Other awards include the NSF CAREER Award (1999), the Xerox Award for Faculty Research (2001, 2005), and the University of Illinois Award for Research with Undergraduates (2002, 2006). Prof. Roth has developed several machine learning based systems that have been used and licensed widely, including an award winning semantic parser. He has presented invited talks in several international conferences including the conference of the American Association of Artificial Intelligence (AAAI-2006), Empirical Methods in Natural Language Processing (EMNLP-2002) and the European Conference on Machine Learning (ECML-2002). Prof. Roth is currently an associate editor for the Journal of Artificial Intelligence Research (JAIR) and the Machine Learning Journal and has been on the editorial board of other AI, Computational Linguistics, and Machine Learning Journals. He was the program co-chair of CoNLL'02 and the program co-chair of ACL'03, the main international meeting of the Association for Computational Linguistics and the natural language processing community. He was also the the president (elected) of SIGNLL, the Association of Computational Linguistics, Special Interest Group on Natural Language Learning (2003-2005).
