Shaman Hatley is a scholar of Asian religions, specializing in the goddess cults and tantric rituals of medieval India, including the yogini cults and the history of yoga. Biography 

Shaman Hatley was educated in liberal arts at Goddard College, graduating in 1998. He then studied Indology and religious studies at the University of Pennsylvania, gaining his PhD on the Brahmayāmalatantra and the Early Saiva Cult of Yoginīs there in 2007; he began teaching at Concordia University that same year. In 2015 he moved to the University of Massachusetts Boston, becoming the chair of Asian studies there in 2020. Hatley's work on the yogini temples of India, starting with his dissertation, brought scholarly attention to their place in translating the purana literature and ritual mandalas into the dramatic circular architecture of these temples.
