Dr. Lindsay Branham is an environmental psychologist, Emmy-nominated film director, and eco-doula. Her debut book, Heartwood: The Wisdom and Healing Kinship of Trees (Hachette 2026), is a non-fiction lyrical exploration of homecoming, wholeness, and healing—weaving science, spirituality, and storytelling to uncover how trees can dissolve the fissure between humans and the living world, and why that bond is healing for ourselves and the planet. Her PhD research at the University of Cambridge, "The Body of the World," pioneered the discovery that interoceptive awareness—our eighth sense—is the key capacity driving an intimate, lasting connection with the Earth that motivates pro-environmental behavior. This finding bridges environmental psychology, embodied cognition, and deep ecology. Lindsay is the founder of Novo Films, a social and environmental impact studio whose film-based interventions have reached 200 million people and raised over $80 million for human and environmental rights efforts across 25+ countries, with significant policy outcomes. She has worked on public health initiatives globally, from the Ebola outbreak in West Africa to scalable mental health and trauma reduction interventions across central Africa and India. She was previously on the team at UC Berkeley's Center for the Science of Psychedelics and taught ecological awareness and ethics. She writes a regular environmental column for The Aspen Times and has been published in The New York Times, The Guardian, and National Geographic.
