Pierre Guetschel
Research
I build foundation models and deep-learning algorithms for neurophysiological signals to advance Brain–Computer Interfaces (BCI): reducing calibration times, increasing robustness, and improving transfer learning. I am interested in whether deep learning can push the limits of what can be decoded from EEG and other neurophysiological signals.
