Timothy Chupp

Professor Chupp and his group undertake measurements of particle properties that probe and challenge the Standard Model of elementary particle interatctions using precision measurement, optical pumping, and nuclear polarization techniques. Recent measurements of the muon magnetic dipole moment anomaly (g-2) to 0.2 ppm and the electric dipole moment of ¹²⁹Xe upper limit of ~10^-27 e-cm are high impact and will be improved in the near future. The other key current direction of Professor Chupp’s research is focused on advances of quantum and optical magnetometers and absolute magnetometry with ³He, the measurement of related fundamental physical constants, and a broad range of applications of magnetic field production and measurements.

Professor Chupp is a Fellow of the American Association for the Advancement of Science, a Fellow of the American Physical Society, and was awarded the 1993 APS I.I. Rabi Prize. He is the founder of Michigan Magnetometry, LLC.
