Database Theory and Engineering Lab

Welcome to the Database Theory and Engineering Lab (DTELab) at the Department of Computing and Software, McMaster University. The DTELab is focused on innovative database research on foundational technologies for future databases, with a strong combined focus on the intersection of theoretical and engineering challenges in the areas of data management and transaction processing.

We are looking for motivated and talented people (at the Master, PhD, and Postdocs levels) with an interest in resilient distributed systems, database theory, or high-performance data management to join our lab. If you are interested, please contact Jelle Hellings with a brief and clear summary of your research interests, a rational as to why your interests fit within the work of our lab, and your qualifications (if you already applied to the graduate school of McMaster University, then also mention your application id).


  1. Our paper The power of Tarski's relation algebra on trees (author copy, project page) recently got accepted for publication in the Journal of Logical and Algebraic Methods in Programming.


Our current research projects focus on distributed data management (with a particular focus on resilience and trust), on graph data (with a particular focus on graph query optimization), and, in general, high-performance data management.
