About me

Currently a postdoctoral fellow with Prof. Dimitri Van De Ville at EPFL. I develop methods related to dynamical systems and graph theory to characterize brain function in healthy and diseased subjects.

My current interests include: spectral graph theory, topological data analysis, time series modelling, brain connectivity, and fMRI. EPFL students interested in doing a project with me can find a list of proposals there.

A January 2020 CV is available here.

News

Where to meet? I will be attending the 2020 Alpine Brain Imaging Meeting in January and OHBM 2020 in Montreal in June. Drop me an email if you want to have a chat.

poetes In November 2019 I co-instigated the Sound of fMRI project at Brainhack Geneva together with Thomas Bolton. Our group identified several original ways to 'listen' to fMRI, including a D- version of resting-state networks activity, or a revisited swan lake, with instruments being weighted by brain function in different networks.

Open notes

Open notes consist of brief reports I wrote to clarify my understanding of research-related questions. I share them here for the use of researchers facing similar problems. Don't hesitate to contact me if you have any question or comment.

Miscellaneous

At the end of my PhD thesis, I represented the University of Liège at the contest "Ma thèse en 180 secondes", inspired from the Three Minute Thesis competition. I started my presentation with this citation by the anthropologist Lyall Watson:

"If the brain were so simple we could understand it, we would be so simple we couldn't."

The variety and the freshness of research conducted in academia is one of my invariable sources of curiosity and pleasure. To highlight the work done by ULg researchers I co-organized the first Pecha Kucha night in Liège during which eight PhD students presented their work to a wide audience. My favorite performances include "How the use of antonyms shapes our representation of the world", "Near death experiences and dualistic questioning", and "The invention of taste".

poetes As a transition between the research stays in Singapore and Switzerland, my wife and I came back to Europe by bike. Along the way we recorded over 40 poets from 13 different countries. "Sur la route des poètes" was designed in collaboration with the Belgian television Canal C for which we produced 10 episodes capturing the essence of our poetic encounters.
