About the Rosen Scholar

The Rosen Scholar is a fellowship created to honor the memory of Louis Rosen, his accomplishments, hard work, and affection for the broad range of science performed at LANSCE. Louis Rosen's outstanding leadership and scientific career at LANL covered six- and-a-half decades and included conception of the Los Alamos Meson Physics Facility (LAMPF), during 1960, that culminated with its commissioning in 1972.

Today LANSCE performs research in materials science using neutron scattering at the Manuel Lujan Neutron Scattering Center, dynamic materials at the Proton Radiography Facility, and applied and basic research in nuclear physics at the ultra- cold neutron facility, WNR, and the Lujan Center.

The Rosen Scholar is reserved for individuals recognized as scientific leaders in a field of research currently performed at LANSCE and who exemplify the innovative and visionary qualities of Louis Rosen. Both experimental and theoretical scientists are encouraged to apply. The Rosen Scholar is expected to be resident at LANSCE and bring his/her scientific expertise to LANSCE as well as the broader Los Alamos scientific community. The position will support the Rosen Scholar at their current salary including relocation expenses for up to one year.

Tim Chupp

Tim ChuppDr. Tim Chupp is a professor of physics, applied physics, and biomedical engineering from the University of Michigan. As Rosen Scholar he will work with the Subatomic Physics group’s Neutron Team to develop the LANL Room-Temperature Neutron Electric Dipole Moment (nEDM) experiment that will used at LANSCE's world-leading Ultracold Neutron Facility. The electric dipole moment is the electrical stretching of neutrons or atoms along their spin axis.

Throughout his career, Chupp haspursued experiments that reveal the nature of elementary particles and the forces between them using hybrid techniques of atomic and nuclear physics. The key tool he has developed with students and collaborators has been control of the spin or polarization of atoms, nuclei, and neutrons using laser techniques. With this special handle, precision measurements of particle energy levels are used to study physics beyond the Standard Model. The Standard Model is the current theory describing interactions between fundamental particles–electrons and quarks–in the universe. However, some inconsistencies in the Standard Model suggest that there might be new physics that cannot be described by this theory. In addition to the LANL nEDM effort, Chupp's team is working on measuring the magnetic moment anomaly g-2 of the muon, studying the decay properties of the neutron and measuring the stretching of the 129Xe atom EDM.

Professor Chupp is a fellow of the American Association for the Advancement of Science and the American Physical Society and was awarded the 1993 I.I. Rabi Prize and a 2019 Gordon and Betty Moore Fundamental Physics Travel Award.
