Paul Guèye, professor of physics at FRIB and in MSU’s Department of Physics and Astronomy, has been named as a 2025 Fellow of the American Physical Society (APS).
APS is the major professional organization for physicists in the United States. It has over 50,000 members from academia, national laboratories, and industry. The mission of the APS is to advance and diffuse the knowledge of physics for the benefit of humanity, promote physics, and serve the broader physics community. Fellows are selected for their outstanding contributions to physics. Each year, the number of APS Fellows elected is no more than one half of one percent of the membership.
Guèye was elected as a Fellow for pioneering experiments and developing tools critical to unravelling the structure of nuclei, and for extraordinary service to the physics community.
“It is a great honor, and I am very humbled to become an APS Fellow,” said Guèye. “FRIB is the only place on earth to conduct the research that my group is doing due to its revolutionary facility. It also pushes us to go beyond our limits of creativity and collaboration that enables scientific discovery.”
Guèye’s research focuses on the study of neutron-rich isotopes near the neutron dripline, which are essential for understanding the formation of heavier elements and the behavior of nuclear matter under extreme conditions. As a member of the MoNA Collaboration, he investigates these exotic nuclei using the MoNA-LISA modular neutron detector and a large-gap superconducting sweeper magnet, contributing to both fundamental nuclear physics and potential societal applications such as in imaging and therapy.
“Congratulations to Paul on being named an APS Fellow,” said FRIB Laboratory Director Thomas Glasmacher. “His pioneering research and dedication to advancing nuclear physics embody FRIB’s commitment to excellence and discovery. This honor highlights the impact of his work and the strength of our scientific community.”
Guèye earned his bachelor’s and master’s degrees from Cheikh Anta Diop University in Senegal and obtained his PhD in nuclear physics from the University of Clermont-Ferrand II in France. He came to the United States as a postdoctoral fellow at Hampton University in Virginia in 1995, contributing to the first experiment to study the elementary production of the strange quark at the Thomas Jefferson National Accelerator Facility. In 2012, he began work with the Modular Neutron Array (MoNA) Collaboration at the National Superconducting Cyclotron Laboratory (NSCL) at MSU, FRIB’s predecessor. He became chairperson of Hampton University’s physics department in 2015 before joining MSU and FRIB as a faculty member in 2018.
Michigan State University (MSU) operates the Facility for Rare Isotope Beams (FRIB) as a user facility for the U.S. Department of Energy Office of Science (DOE-SC), with financial support from and furthering the mission of the DOE-SC Office of Nuclear Physics.
