Jacques Carolan — The Mission to Get Breakthrough Brain Treatments to Everyone

Juan Benet

Juan Benet

Biohybrid interfaces, closed-loop gene therapies, and the push to put transformative brain technology in every clinic.

Episode 3 features Dr. Jacques Carolan, a founding Program Director at ARIA, the UK’s Advanced Research and Invention Agency. He directs two neurotech programs aimed at one of the most important opportunity spaces: developing tools and systems to interface, at scale, with the human brain.

One program is built on the idea that brain disorders are circuit problems, and funds tools to target those circuits with molecular precision across the whole brain. The other aims to deliver high-performance neurotech to the brain non-invasively, or at most in a 30-minute outpatient procedure.

We dig into the engineering and biology behind both programs, potential scaling unlocks for the field, how ARIA programs drive breakthroughs, Jacques’ background, the role of media in shaping the future, and much more.
