He is the Fay R. and Eugene L. Langberg Professor of Physics and Co-Director of the Center for Particle Cosmology at the University of Pennsylvania.

In 1992, Trodden moved to the United States to enter the Ph.D. program at Brown University and obtained his Ph.D. degree in 1995.

Trodden, with Sean Carroll, introduced a new class of topological defects in ordinary field theories.

Trodden's work in theoretical studies and understanding of the early universe has been widely cited and relied upon by the scientific community.

[3] Specifically, Trodden's research focuses on configurations consisting of topological solitons which end on others of equal or higher dimension.
