Torn between two compelling career paths, Mississippi State junior Anthony Mattina is navigating the intersections of faith and science—a journey shaped by a love for both the mysteries of the universe and the traditions of the Catholic Church.

“I’m currently deciding between two career paths with my physics degree,” said Mattina, a self-described “cradle Catholic.”

“Originally, I wanted to become a cosmologist at the Vatican, reporting to the pope about cosmic happenings and their relation to Catholic teachings. Recently, though, I’ve developed a passion for medical physics.”

That passion stems from personal experience. “Several people close to me have fallen victim to cancer, leading to my growing desire to fight this terrible disease,” said the Biloxi native.

Mattina’s fascination with physics began in high school during the pandemic. “All there was to do was browse the internet. I stumbled upon astrophysics videos and couldn’t get enough. I sought out different theories to study and decided this was something I could spend a lifetime learning.”

He now is majoring in physics with minors in mathematics and religion. His religious studies reflect a broader goal: “I want to convince others that religion and science aren’t mutually exclusive, but rather complement each other. Physics helps me understand the intricacies of God’s creation.”

Though the idea of becoming a Vatican cosmologist still appeals to him, medical physics offers a more immediate way to make a difference. “When I shadowed in a hospital, I knew I’d enjoy this as a career,” he said.

Mattina is already deeply engaged in research that mirrors his dual interests. At MSU, he works with Professor Dipangkar Dutta on a nuclear physics project with quantum implications. As a student researcher with the University of Mississippi Medical Center, he’s part of a radiation oncology team training software to automate the patient remapping process—cutting the time between diagnosis and treatment.

Balancing it all—faith, studies, research and even a deep personal interest in genealogy—requires careful planning. “It comes down to priorities. Faith, family, school, and then the fun stuff,” he said.

His advice to students with multiple interests: “Give it a semester before you add the second or third thing. For students who feel ready, find space in your schedule to try a new class before committing.”

As for choosing between careers?

“Ultimately, it’s what God calls me to do.”
