Bio:
I joined Waterloo in 2011 and was awarded a Canada Research Chair in 2015.
From 2006 to 2011 I was a Senior Member of Research Staff at AT&T Labs.
I have a BSc in Computer Science from the University of Toronto (with High Distinction) and a PhD in Computer Science from the University of Waterloo (with Alumni Gold Medal).
My recent research interests include decentralized, explainable and trustworthy data systems.
Current and upcoming professional service:
Associate Editor for SIGMOD 2023 and Information Systems;
Area chair for ICDE 2024;
PC Member for SIGMOD 2024, EDBT 2024, and SSDBM 2023;
Review Board Member for PVLDB 2022/23
