I am a neuroscientist working at the interface of neurophysiology, neuroimaging and applied mathematics.  Im fascinated by how the brain self-organizes, diversifies and adapts – and Im using math as a microscope.

How can the brain express such a rich yet stable repertoire of dynamics? What goes wrong in case of diseases such as epilepsy, multiple sclerosis and depression? What can we do about it?

To answer these questions, my team and myself are trying to close the gap between experiments, modelling and biomedical applications, using data, computation and math.  Currently, my interdisciplinary lab explores 1) white matter plasticity and neuron-glia interactions; 2) How seizures occur in neural circuits, why, and what can we do prevent them; 3) Optimize techniques of neural control and non-invasive brain stimulation.
