Welcome to the OpAL Lab

The Optimization, Analytics and Learning (OpAL) Lab is a research group at the Cheriton School of Computer Science. Our work is focused on machine learning on graphs, which is about making predictions using multi-modal datasets that combine features and relational information among entities. Our work involves stronger control on optimization formulations and algorithms, as well as their parallel and communication efficient implementations. We are equally interested in theory and in practice.

We are located at the University of Waterloo, a vibrant technological hub with Concept, Velocity and Google around the block. We are also part of the Scientific Computation Group.

We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !

We are grateful for funding from the University of Waterloo and NSERC
