Dr. Hugh Williams is internationally recognized as an expert in computational number theory and its application to cryptography; in particular, he is a world authority on computing in number fields. After obtaining his PhD in 1969 from the Department of Applied Analysis and Computer Science at the University of Waterloo, he joined the newly established Department of Computer Science at the University of Manitoba, where he was promoted to the rank of Full Professor in 1979. He moved to the University of Calgary in 2001 where he became iCORE (Alberta Informatics Circle of Research Excellence) Chair for Algorithmic Number Theory and Cryptography, and Professor in the Department of Mathematics and Statistics.
Dr. Williams is widely published in the field of computational number theory, and from 1983-85he held a national Killam Research Fellowship, one of the most prestigious honours in Canadian Research. In 2004 he was appointed Professor Emeritus at the University of Manitoba. He co-founded the University of Calgary's Institute for Security, Privacy and Information Assurance (ISPIA). He is actively involved in speaking and outreach engagements, delivering a number of distinguished lectures including the keynote speaker address at the 2004 Workshop on Cryptographic Algorithms and their Uses (Gold Coast, Australia). Additionally, he sits on the Board of Directors of the Number Theory Foundation, the Pacific Institute for the Mathematical Sciences, and the Canadian Mathematical Society.
In February 2009, Dr. Williams was appointed Director of the Tutte Institute for Mathematics and Computing (TIMC).
