After completing his undergraduate training in philosophy, theology and mathematics in 1947, he went to the Pontifical Institute of San Anselmo, Rome, where he received a doctorate in theology in December 1950. In 1948 he was ordained a priest.

From 1951 Dr. Jaki taught systematic theology at the School of Theology of St Vincent College, Latrobe, Pennsylvania. During this time, he attended in the same college courses in American history, literature, mathematics and sciences to secure American recognition of his undergraduate training done in Hungary. He received his BS from St Vincent College in 1954. The same year, he began doctoral research in physics in the Graduate School of Fordham University, New York, under the mentorship of the late Dr. Victor F. Hess, the discoverer of cosmic rays and a Nobel-laureate. Dr. Jaki’s thesis was published in the June 1958 issue of Journal of Geophysical Research under the title, “A Study of the Distribution of Radon, Thoron, and Their Decay Products Above and Below the Ground.” Between 1958 and 1960 he did research in the history and philosophy of physics at Stanford University and the University of California, Berkeley. From 1960 to 1962 he was Visiting Fellow in the Program for the History and Philosophy of Science at Princeton University. From 1962 to 1965 he wrote the important work, The Relevance of Physics (University of Chicago Press, 1966). Beginning in 1965 he was on the faculty of Seton Hall University and he was promoted in 1975 to the rank of Distinguished University Professor. In 1966-67 he was associated with the Institute for Advanced Study Princeton, and later served as a Visiting Professor at Princeton Theological Seminary (1981) and a Fellow in the Center of Theological Inquiry, Princeton (1984-87, 1989-90).
