# Timothy E. Chupp

Timothy E. Chupp is an American scientist and educator and is currently a Professor of Physics and Biomedical Engineering at the University of Michigan. He has also taught at Princeton and Harvard.
Chupp is fellow of the American Association for the Advancement of Science and a fellow of the American Physical Society. In 1993 he was awarded the I. I. Rabi Prize. In 2020 he was named the Los Alamos National Laboratory LANSCE Rosen Scholar.
He has broad-ranging interests in experimental physics, precision measurement in particle physics, and applications in metrology and biomedicine. He is also the founder of Michigan Magnetometry LLC.

## Education

Chupp earned his B.S. in physics from Princeton in 1977, and his Ph.D. from the University of Washington in 1983.

## Research

Chupp has broad research interests in experimental physics, including particle physics, atomic physics, and nuclear physics. His applied work includes precision magnetometry, nuclear magnetic resonance and MRI with laser polarized xenon. He has co-authored over 170 papers.
His most recent work uses precision measurement techniques and symmetry principles in particle physics investigations, applied to a wide variety of research questions, including measurement of the anomalous magnetic dipole moment (g-2) of muons at Fermilab, as well as atomic and neutron electric-dipole-moment measurements. The results of this latest research challenge the Standard Model with new precision measurements that deviate from Standard Model predictions well beyond experimental error.

## Public lectures

Chupp has given a number of lectures to the public, including for the University of Michigan Saturday Morning Physics program and Sloan Foundation Science and Film Series and other channels, on topics including on muons, solar neutrinos, the physics of vision, and the physics of baseball and basketball.
