Since 2000 Brian Collett has been collaborating with Hamilton's Gordon Jones on projects in nuclear physics. Their work has included the development of compact 3He neutron spin filters for use in neutron scattering, and they are participants in the aCORN experiment, studying neutron decay at the National Institutes of Standards and Technologies.

Collett and Jones are responsible for the magnetic and electric fields in the experiment and have contributed extensively to the data collection and analysis. Before coming to Hamilton in 1986, Collett was a staff fellow at the National Institutes of Health and a visiting assistant professor of physics at Mt. Holyoke College. He received a doctorate from Princeton University.
