About

A multidisciplinary engineering profile

From electromagnetic simulation to embedded acquisition and machine learning, my work connects modelling, hardware and experimental validation.

I hold a Master 2 in Signal and Telecommunications from Bretagne INP — ENIB, following a Master 1 in Embedded Electronic Systems and a Bachelor’s degree in Biomedical Engineering.

My projects span RF and microwave characterization, sensor-based electronics, autonomous energy systems, embedded acquisition, digital communications, multimedia processing and deep learning. I particularly enjoy problems where theoretical modelling must be confronted with real measurements.
