is an anthropologist based in Brighton, Sussex, working as a writer and lecturer on magical consciousness. When she first started her doctoral research in the 1990s on British practitioners of magic she decided to study magic from the inside, as a practitioner herself. Thus she explored various approaches to magic and participated in many witchcraft rituals, was trained as a high magician and worked with shamans. Greenwood then linked her practical experience to a scholarly approach aiming to build bridges between magical practice and academic discourse. Having gained her PhD in anthropology in 1997, she has lectured at Goldsmiths, University of London, and the University of Sussex, and has taught courses on the anthropology of religion, shamanic consciousness and altered states of consciousness. In 2014, Greenwood was invited as a researcher to contribute to a seminar on the paranormal at the Esalen Center for Theory & Research in California. Her publications include Magic, Witchcraft and the Otherworld (2000), The Nature of Magic (2005), The Anthropology of Magic (2009), Magical Consciousness: an anthropological and neurobiological approach (with Erik Goodwyn, 2015), Developing Magical Consciousness (2019) and Astral Magic, Consciousness and the Imagination in Astral Bodies (2017). She lectures internationally, and recently gave a keynote to the Danish Ethnographic and Anthropologist Societies at the University of Copenhagen and a lecture on the subject of exploring magic in art at the Migros Museum für Gegenwartskunst, Zurich.

Keller, who now lives in Berlin, examines phenomena from the natural sciences from an artistic perspective, and also researches topics from fringe science such as the relation between hypnosis and cinematography.
