Mac is a PhD candidate in the Study of Religion. He studies the relationship between Christian theology and political thought, principally in relation to far-right white nationalisms in the twentieth century and today. His research explores theology as a site of contestation in times of crisis, drawing on psychoanalytic and poststructuralist theories of subjectivity and relation as well as theologies of incarnation, sacrament, repentance, and vulnerability. Other interests include medieval mystical theologies, religion and literature, and theologies of grief and mourning in relation to the climate crisis.

Mac received a B.A. in Philosophy, Classics and Religion from Boston University in 2015 and a M.Div. from Harvard Divinity School in 2018.
