Research Interests

Computational Neuroscience, Motor Control, Neuroimaging, Brain/Body Machine Interface

We do research in Computational Neuroscience with a special focus on Motor Control, Decision Making, Multi-sensory Integration & Sensory-Motor Coupling. In particular, we use computational methods from Machine Learning (Dimensionality Reduction, Classification, Regression etc), Signal Processing and Information Theory to analyse and model high-dimensional neural, biomedical and behavioural signals.
