Dr. Chelsea Matisz is an award-winning gut–brain scientist, keynote speaker, and science communicator who integrates neuroscience, microbiome science, inflammation, and human behavior. She holds a MSc in evolutionary biology, a PhD in Gastrointestinal Sciences, and has several Neuroscience fellowships, focusing on gut physiology, stress, and microbiome–brain interactions.

Today, Chelsea helps people understand how the gut–brain axis and microbiome shape stress, energy, mood, motivation, decision-making, performance, aging, and women’s health. She translates complex, cutting-edge biology into clear, actionable insights—empowering audiences to work with their bodies instead of against them, and improve their mental and physical wellbeing using science they can actually apply.

Her TEDxCalgary talk, The Ancestral Paradox, reveals how ancient stress programs collide with modern living and introduces a compassionate framework for working with, rather than against, your biology.
