T-RIZE Lab (FUSÉE Lab) @ ÉTS Montréal

Introduction

Welcome to the webpage of the T-RIZE lab (FUSÉE Lab) at the Department of Software and IT Engineering, ÉTS Montréal (University of Québec). FUSÉE is a research group composed primarily of graduate students, established in 2017 by Dr. Kaiwen Zhang. Our mission is to study and build distributed systems based on five aspects:

Fast, high-velocity, Big Data processing to achieve online analytics.
Unified and secure event-based frameworks for domains such as social networks, Internet of Things, online gaming.
Scalable distributed and decentralized systems to handle large volumes of data and users.
Event processing to support streaming operations such as aggregation, top-k filtering, and complex event detection.
Event messaging using the publish/subscribe abstraction for decoupled networked interactions.

Research Projects

Practical Blockchain & DLT

Blockchain-based distributed ledger technology (DLT) processes and disseminates transaction events in a decentralized network. Our objective is to achieve the right balance of decentralization, consistency, and scalability to meet the requirements of important domains such as eHealth, IoT, and Smart Grids.

Expressive Publish/Subscribe

Modern applications (e.g. social networks, sensor networks) require advanced analytics over real-time streams of events. We strive to support these expressive features without compromising performance or scalability by integrating lightweight distributed processing techniques into the publish/subscribe communication substrate.

Networked Game Engines

Networked games require low-latency, reliable, and cheat-resistant communication between players. We aim to develop scalable infrastructures for highly-interactive online games. By leveraging game semantics, such as player profiles and the virtual environment, we can achieve the right trade-off between consistency and performance.

Team

Principal Investigator

Kaiwen Zhang is an Associate Professor in the Department of Software and IT Engineering at ÉTS Montréal (University of Québec). Previously, he was an Alexander von Humboldt postdoctoral fellow in Computer Science at the TU Munich (2015-2017) and a member of the Middleware Systems Research Group. Dr. Zhang obtained his B.Sc. and M.Sc. at McGill University in Montréal and his Ph.D. at the University of Toronto. His research interests include blockchain technologies, publish/subscribe systems, massively multiplayer online games, and software-defined networking. Dr. Zhang's expertise lies at the intersection of distributed systems, networking, and data management. His research is published in premier distributed systems conferences such as IEEE ICDCS and ACM Middleware.
