- Core research problem: How to design compact, robust, and high-performance wideband RF direction-finding systems by jointly optimizing antennas, RF front-ends, radomes, and signal processing for harsh and constrained environments.
"Optimizing each subsystem is not enough, performance comes from co‑design."

Sylvain Dubois is a first‑year PhD researcher in electrical engineering, specializing in RF systems and signal processing.
His work combines antenna design, RF front‑end architectures, and signal processing for wideband direction finding.
He is interested in industrial valorisation, intellectual property, and technology transfer.
Community engagement and outdoor sports play an important role in his life outside research.
Designing Robust RF Direction‑Finding Systems
Sylvain's doctoral research addresses the design and implementation of wideband RF direction‑finding systems operating from 2 to 18 GHz. His work spans antenna arrays, front‑end architectures, and signal processing algorithms, with a strong focus on compact and robust solutions.
A key insight from his research is that overall system performance depends on the interaction between subsystems. Antenna behavior, electromagnetic effects from radomes, and signal processing choices must be considered together, particularly in constrained maritime environments.
From Subsystems to System‑Level Thinking
Through practical experience, Sylvain has learned that optimizing individual components in isolation is insufficient. Instead, a global co-design approach is required to ensure reliability across wide frequency bands and real-world operating conditions.
"The environment and the platform matter just as much as the technology itself."
Industrial Valorisation and Innovation
Beyond research, Sylvain is deeply interested in the industrial valorisation of RF and electromagnetic systems, particularly in defence, maritime technologies, and autonomous platforms. He is curious about intellectual property strategies and how strong technical differentiation translates into patents and innovation.
Having already experienced collaboration with an industrial partner, he is keen to understand how such partnerships can evolve into structured innovation processes or entrepreneurial opportunities.
Teamwork, Leadership, and Community
Outside the lab, Sylvain is highly involved in community and team-based activities. As an active member of his laboratory's PhD association, he organizes sports sessions and group events, experiences that reinforce his interest in teamwork and leadership.
Motorsports and outdoor sports further fuel his fascination with the link between technology, performance, and real-world constraints.
"I want my research to leave the lab and prove itself in demanding environments."
