Neuronal gene expression is studied in the context of individual synapses, synaptic circuits and behavior. Optogenetic tools and neuronal interfaces are applied in vitro and in vivo to cellular and animal models of brain function and neurodegenerative diseases. Main interests are: neurogenomics, cellular neurophysiology, behavioral neuroscience and the development of new technologies for brain research.

Photonic Neurosurgery Lab

Neuroscience research has recently taken advantage of optical approaches to record, modulate and manipulate the physiological activity of neurons. Our work focus on the development of optical systems for the precise and controlled spatio-temporal manipulation of biological samples, and on the integration of optical setups with electrophysiological recording devices to study the central nervous system at various levels of complexity.
