Shannon Hoogerheide is a staff physicist in the Neutron Physics Group at the National Institute of Standards and Technology (NIST). Her research focuses on precision measurements of fundamental physics using neutrons, including experiments to measure the neutron lifetime and the spin rotation of polarized neutrons. She is also involved in neutron interferometry, detector development, and neutron irradiations and calibrations. She received a B.S. in Physics from Calvin College and an A.M. and a Ph.D. in Physics from Harvard University, where she worked on measurements of the electron and positron magnetic moments. Prior to joining the Neutron Physics Group, she was a National Research Council Postdoctoral Fellow in the Atomic Spectroscopy Group at NIST where she worked with highly charged ions.


Measuring the Neutron Lifetime with Record-Breaking Precision

An improved version of a “bottle” experiment lets researchers lower the uncertainty on this important parameter—but a tantalizing discrepancy remains. Read More »
