The Master of Mathematics in Data Science (DS) is a new thesis-based Master’s program in the Faculty of Mathematics, in which students work on a Data Science-related topic with a research supervisor in the field of DS. This program is designed to strategically leverage the breadth and depth of research that currently exists in the Faculty of Mathematics in the field of DS. It does so by offering an integrated and interdisciplinary approach to Data Science that can be best achieved with the three supporting academic units, namely the Cheriton School of Computer Science, the Department of Combinatorics and Optimization, and the Department of Statistics and Actuarial Science. Because of this unique and high-quality training, graduates of this program is anticipated to be in high demand, capable of conducting research in industry or academia within Canada and abroad upon graduation. This program aims to integrate knowledge from computer science, statistics, and optimization, develop expertise in the field of Data Science, and enable the development of original research.  In addition, the research program strives to achieve a thorough understanding of the existing methods and techniques used in Data Science, and adapt them to create new and improved solutions.
