ABOUT THE SPEAKER
Jocelyne Bloch - Functional neurosurgeonJocelyne Bloch is helping to unlock potential self-healing capacities of the human brain.
Why you should listen
Swiss neurosurgeon Jocelyne Bloch is an expert in deep brain stimulation and neuromodulation for movement disorders. Her recent work focuses on cortical cells, called doublecortin, related to neurogenesis and brain repair. In collaboration with Jean François Brunet and others, she is pioneering the development of adult brain cell transplantation for patients with stroke, using their own stem cells. She aims at gathering all these novel therapeutic strategies under a common umbrella that will optimize treatment options for patients suffering from neurological impairments. She is in charge of the functional neurosurgery unit at the Lausanne University Hospital (CHUV).
