Alex K. Gearin (PhD) is a cultural anthropologist specializing in the intersections of mental health, neo-shamanism, and psychedelics. Much of his research has focused on ayahuasca, including for his recent book Global Ayahuasca: Wondrous Visions and Modern Worlds (Stanford University Press, 2024). The book explores how the emotional and sensory dimensions of ayahuasca practices intersect with modernity and globalization, based on ethnographic research on the ground in Australia, Peru, and China.
