In a field moving this fast, it's important to remember that everything we take for granted was someone's lifetime of dedication. In our journey to collect their untold stories we catch up with one of the fields heroes, Jean-Francois Aubry, the Director of Research at the French National Center for Scientific Research, the Scientific Director of the Focused Ultrasound Foundation Center of Excellence at Physics for Medicine Paris, and co-founder of SonoMind. This episode is a wealth of historical context for acoustic array and lens design, through-skull transmit-receive, first steps in safely modulating the brain, scientific mentorship, and a forward looking sentiment for the mass treatment of depression. It is an absolute must listen for all those in the space.
