LLoyd Newton, Ph.D., came to St. Mary’s University in the spring of 2017. Currently, he teaches Latin for the Department of Languages and Philosophy Department. Prior to coming to St. Mary’s, he taught at the Katholieke Universiteit in Leuven, Belgium, which is the oldest extant Catholic university in the world, and at Benedictine College. Newton’s specialty is medieval philosophy, especially Duns Scotus. He has translated and published Scotus’s Questions on Aristotle’s Categories.

Although he grew up in West Texas, he loves living in San Antonio and is excited to be a part of St. Mary’s.
