About me

I am a Research and Teaching Fellow jointly at the University of Geneva and EPFL. I set up neuroimaging experiments and I develop methods to characterize brain function in healthy and diseased subjects.

My interests include fMRI, EEG, neurofeedback, dynamical systems theory, and brain connectivity. Students interested in doing a project with me can find a list of proposals there.

A June 2022 CV is available here.

News

• In June 2022 I organized the first EPFL Causality Workshop with speakers from seven different countries discussing various aspects of causality. All talks are available from a dedicated SwitchTube channel.

poetes • We were back in person for the fifth edition of our course on 'Brain Dynamics: Methods and Clinical Applications' at OHBM 2022 in Glasgow -little pic with dream team attached. See you in June 2023 for the sixth edition.

• In February 2022 my first PhD student defended his thesis, congrats Dr. Miljan Petrović!

• In Fall 2021 I gave my first course at the University of Geneva on 'Causal Inference for Time Series Analysis'. More information on the 2022-2023 course coming soon.

Open notes

Open notes are brief reports I wrote to clarify my understanding of research-related questions. I share them here for researchers exploring similar questions. 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.
