Research

My research focuses on two areas: understanding energy deposition in low-threshold detectors, and building software solutions that solve common data, software, and analysis problems for the nuclear physics community and broader communities that also depend on data.

I am a member of the Cryogenic Dark Matter Search collaboration, which specializes in sensing the faintest possible signals from highly-sensitive phonon detectors.  This collaboration searches for “dark matter” particles, which are hypothesized to make up fully 80% of the universe’s mass but have never been directly detected.
