On July 1, 2020, he became the Dean of the Faculty of Mathematics at the University of Waterloo.

Research 
Giesbrecht’s research is in computer algebra, where he has proved a number of fundamental results, including on the complexity of computing matrix normal forms, solving sparse diophantine linear systems, and non-commutative polynomial algebra. More recently he has been on the forefront of an optimization approach to symbolic-numeric algorithms for matrix polynomials.

Awards 
As a member of the Cheriton School of Computer Science's Symbolic Computation Group, Giesbrecht shared the 2004 NSERC Synergy prize for innovation under the prize's small- and medium-sized companies category. In 2012 he was named an ACM Distinguished Scientist.
