Penn State physicist honored with 2025 Lars Kann-Rasmussen Prize

2025-02-20

Jacob Bourjaily, associate professor of physics, was honored with the Lars Kann-Rasmussen Prize for 2025 by the Niels Bohr International Academy (NBIA), in Copenhagen, Denmark. The prize is awarded annually to an exceptionally talented young individual who has had very high impact in research and has or has had close connections to the Niels Bohr Institute. Bourjaily was presented the prize by Lars Kann-Rasmussen, former chairman of the board of VKR Holding and the Villum Foundation, at an award ceremony on February 24 that was attended by the head of the Niels Bohr Institute Joachim Mathiesen, Deputy Dean of Research Lise Arleth, and NBIA Director Poul Henrik Damgaard.

“I am extremely grateful for the generosity and support I was given during the nearly ten years I spent at the Niels Bohr Institute and International Academy,” Bourjaily said. “Through the generosity and support of the Danish people and the Niels Bohr Institute, I was able to build and lead the world’s largest team of postdoctoral scholars studying exciting new developments in quantum field theory. It is a great honor to be awarded this prize for the work that was started there.”

Bourjaily was awarded the prize “for his fundamental and original contributions to quantum field theory, guided by an on-going quest for both simplifications and deeper understanding.”

Bourjaily is a theoretical physicist whose research revolves around quantum field theory — the basic theoretical and mathematical framework that combines quantum mechanics with relativity. He works to revolutionize how quantum field theory is used to make predictions for experiments. Among the most important of these predictions are scattering amplitudes, which encode the predicted relative likelihoods of all possible outcomes of any experiment. Bourjaily’s research has led to great advances in the ability to make such predictions and in understanding the mathematical form that these predictions take.

About our wordmark
Monica The IGC wordmark was created by Monica Rincon Ramirez, while she was a graduate student at the Institute for Gravitation and the Cosmos (IGC). Monica enjoys drawing new connections between fundamental theory and observations. Her graduate work includes specialized topics in general relativity, loop quantum gravity, and quantum fields in cosmological backgrounds. In particular, her thesis work focused on finding effective quantum corrections to gravitational phenomena from spinfoams, and applications to cosmology. She received her PhD in 2024.

The wordmark symbolizes the scope and variety of research at the IGC. The base of the image represents quantum gravity, evoking the quantum geometrical picture from spinfoams and loop quantum gravity. These are among the approaches to fundamental questions studied at the Center for Fundamental Theory. The middle of the image represents the Center for Theoretical and Observational Cosmology by galaxies embedded in a smooth surface, characteristic of spacetime in general relativity and the much larger physical scales studied in cosmology. Finally, at the top, the surface curves to an extreme, representing a supermassive black hole accompanied by an energetic jet. These elements depict an active galactic nucleus, inspired by Centaurus A. Just to the right, a pair of black holes approaches merger. This top portion of the wordmark represents the Center for Multimessenger Astrophysics, which specializes in the study of high-energy phenomena in the universe.
