Biography

Dr. Dimitrios Diochnos is an assistant professor in the School of Computer Science at the University of Oklahoma (OU). Prior to joining OU, he worked as a Hobby postdoctoral research fellow at the Department of Computer Science of the University of Virginia. Earlier he held a research associate position at the University of Edinburgh. He received his PhD degree from the Department of Mathematics, Statistics, and Computer Science at the University of Illinois at Chicago. He received his MS degree from the Department of Mathematics at the University of Athens, Greece. He received his BS degree from the Department of Informatics and Telecommunications at the University of Athens, Greece. The main focus of his research is on the mathematical foundations of machine learning. He is also interested in artificial intelligence at large and in particular in applications of knowledge-based systems to automated reasoning. His work has appeared in top conferences such as NeurIPS, ALT, and FUN, or top journals such as Information Processing Letters and Journal of Symbolic Computation. He has served as a member of the program committee in major artificial intelligence venues such as NeurIPS, AAAI, and IJCAI. He has also served as a reviewer in top venues such as SODA, ICALP, and AAMAS, or top journals such as SIAM Journal on Discrete Mathematics, Discrete Applied Mathematics, and Annals of Mathematics and Artificial Intelligence. Since 2012 he has served as the publicity chair for the biennial International Symposium on Artificial Intelligence and Mathematics (ISAIM). He is also a co-editor on a special issue of the Annals of Mathematics and Artificial Intelligence journal, devoted to ISAIM 2018. Finally, he has also served as a member of the international scientific committee for the International Olympiad in Informatics in 2004.
