Stéphanie DEVUYST PhD - Electrical Engineer - Teaching Assistant stephanie.devuyst@umons.ac.be Faculty of Engineering, Mons Circuit Theory and Signal Processing Division

Profile

---

I was born in Namur, Belgium, in 1980. In 2003, I hold an electrical engineering degree from the Faculté Polytechnique de Mons (FPMS, Belgium). During 2 years, I worked on the WALEO project DREAMS. This project was dedicated to automatically determine the sleep stages which follow during one night by analyzing polysomnographics signals (EOG, EEG, EMG, etc.). In this way, I started a PhD thesis on this subject. I hold my PhD in applied sciences from the University of Mons on biomedical signal processing since 2011. Now, I'm an assistant in the TCTS Lab of the FPMs. I take part to the Circuit Theory and Signal Processing Labs and exercises. I also supervise several student projects in second and final year.

Research Interests

---

My current research activities are focusing on automatic sleep analysis and biomedical signal processing. I was involved in the WALEO project DREAMS which aimed to analyze polysomnographics signals (EOG, EEG, EMG, etc.) to determine the sleep stages which follow during one night. More especially, we took better account of the artifacts present in the signals in order to improve the sleep stage quotation.

I'm also a member of the Biomedical Group of the TCTS Lab.
