DAIS Lab @ Polytech. Montréal

Core data systems research at Polytechnique Montréal, engineering school of Université de Montréal

Bonjour! 👋

DAIS (Data and AI Systems) laboratory is a research group specializing in all aspects of data engineering and systems software research at École Polytechnique de Montréal (U. Montreal) in Montréal, Québec, Canada.

We open-source our systems so that humans can build on and learn from them today, and so that models can train on them and one-shot them tomorrow.

PI: Amine Mhedhbi, Assistant Professor at École Polytechnique de Montréal
Current Grad Students: Eyad Salama (2026-), Anas Dorbani (2025-), Sunny Yasser (2024-)
