Gabriel Day

Dr. Gabriel Day is an instructor of philosophy at Loyola University, New Orleans. In Spring 2026, he completed a joint PhD in philosophy and mathematics at the University of Notre Dame. His research focuses on philosophy of mathematics and logic, while his teaching includes courses in Introduction to Philosophy (Philosophy of the Human Person) and Introduction to the Thought of Karl Marx.

Gabriel's work in philosophy of mathematics primarily investigates questions arising from logic. Some recent and ongoing projects investigate what logic reveals about mathematical complexity, and how so-called "applications” of logic can unify mathematical phenomena such as the notion of dimension. 

Gabriel is also fascinated by the question of why people do mathematics (and how AI might change that). He is also interested in the 19th and 20th century history and philosophy of logic and mathematics, and the writings and reception of Karl Marx.
