Research Interests

I am a member of the Rare Event Detection group. We build and operate high-precision radiation detectors and develop algorithms aimed at detecting highly elusive particle interactions. My focus is specifically on direct neutrino mass measurements and WIMP dark matter detection. I am also involved in nuclear nonproliferation experiments involving highly efficient neutron detectors, scoping studies for use by the IAEA, as well as high-energy photon active interrogation to search for shielded SNM. Applied work also includes development of a small form factor nuclear battery.
