I am a mathematician and have been on the faculty of Christendom College since 2017. I received my Ph.D. in Mathematics from the University of Nebraska-Lincoln in 2016. My research area was commutative algebra, and my dissertation employed methods of homological algebra. Currently, I am more focused on studying historical and philosophical questions in mathematics. In particular, I am interested in questions related to the foundations of mathematics as well as mathematics’ place within a liberal arts education.
