Xander Cadisch

Xander Cadisch is Co-Owner of Phos and Founder of Light Tribe by Phos, working at the intersection of light, human biology, neuroscience, and the built environment. He is the author of the international award-winning The Light Within Us, which reframes light as a biological input that shapes health, emotion, cognition, and performance, combining ancient biology with modern scientific research to explore how we design healthy environments for an indoor species. Building on this work, Xander is developing a next-generation global framework for healthy lighting in the built environment, bringing together circadian science, photobiomodulation, neuroaesthetics, neuroarchitecture, spectral biology, and practical design application through global research, academic collaboration, and direct conversations with some of the world’s leading scientists, architects, designers, neuroscientists, and wellbeing pioneers. He is also the creator and host of the In Light of It All, now in its third season
