A Chemist's Conversion to Catholicism (Dr. Stacy Trasancos)

Dr. Stacy Trasancos joins Fr. Mark Mary for a wide‑ranging conversation on science, faith, and the limits of materialism. A former senior research chemist at DuPont with a PhD in chemistry, Stacy shares her journey from atheism and a strictly materialist worldview to Catholicism, theology, and philosophy.

Together they explore how science was born from faith, why materialism fails to explain human dignity and meaning, and how philosophy and theology help restore a fuller vision of reality. From transubstantiation and the Eucharist to evolution, AI, and ethics in modern science, this episode offers a hopeful and intellectually rigorous vision for evangelizing through reason.

Dr. Trasancos is an adjunct professor at Holy Apostles College and Seminary, holds graduate degrees in theology and philosophy, and is currently pursuing a doctorate in philosophy in Ireland.

In this episode of Power & Witness, Fr. Mark speaks with Fr. Christopher Seith, priest of the Archdiocese of Washington, DC and Coordinator of Spiritual Formation at St. John Paul II Seminary.

Anthony Giambrone, OP to explore the continuity and transformation of the priesthood from Scripture into the life of the Church today.
