Machine learning for time series and brain signal


After a PhD on bio-inspired robotic vision at LIMSI CNRS, I was a post-doc fellow in the neurocybernetic team of ETIS. I embraced a more machine learning centric approach to analyse EEG for Brain-Computer Interface (BCI) during two post-doc, one at TAO INRIA and one at Telecom ParisTech. I am now assistant professor in LISV - University of Versailles where I work on BCI for rehabilitation robotics.
