Bio

Dr. Pattie completed his Ph.D. in experimental nuclear physics in 2012 at North Carolina State University. After graduating he took at joint Postdoctoral Research position at North Carolina State University and Fermi National Accelerator Laboratory to work on a proposed neutron-antineutron oscillation search experiment at the Project X upgrade. In 2014 he joined the Neutron team in Los Alamos National Lab's Subatomic Physics group (P-25) as a Postdoctoral Research Associate working on the UCNτ experiment and the upgrade of the ultracold neutron source for a new room temperature neutron electric dipole moment search. After three years at Los Alamos he taught for a summer at Indiana University and in 2018 joined the Department of Physics and Astronomy at East Tennessee State University as an Assistant Professor.

Research Interests

I use cold and ultracold neutrons to study the fundamental symmetries of nature. Precision measurements of the neutron decay parameters can search for physics beyond the standard model. Searching for the neutron's permanent electric dipole moment probes for new sources of charge-conjugation and parity violation, key components in understanding why we live in a matter dominated universe.
