    8. Farah Lubin, PhD on epigenetics and the brain

    In this episode, I sit down with Dr. Farah Lubin, a neuroscientist from the University of Alabama at Birmingham, to explore the fascinating world of epigenetics in the brain. Dr. Lubin shares her groundbreaking research on how gene expression can influence memory formation and neurological disorders like epilepsy. We also discuss how understanding these mechanisms could lead to novel therapies, along with the transformative power of epigenetics in brain science. Follow along as Dr. Lubin walks us through her unique career journey and sheds light on the evolving field of neuroepigenetics.

    5. Stephen Coombes, PhD on neural field theory

    In this episode, I talk with Stephen Coombes, Ph.D. about neural field theory, or the theory of brainwaves. Dr. Coombes is Professor of Applied Mathematics in the School of Mathematical Sciences at the University of Nottingham. We explore the foundations of neural field theory, how it models large-scale brain activity, and its relevance to understanding states of consciousness, visual hallucinations, and working memory. Dr. Coombes shares insights from his journey from theoretical physics to neuroscience, and we discuss the future directions and challenges in this fascinating field of study.

    In this episode I talk with clinical psychologist Jay Skelton, Ph.D. and software engineer Andrew Leker about Willow. Willow is a new, empathetic AI specifically designed to be a mental health tool (and not a replacement for a licensed therapist). We take a deep dive into how Willow was trained, how strict safety guardrails were put in place, how Willow is already being used in mental health clinics, its privacy, and the future of AI for mental health.
