My Research on Dark Matter Detection Astronomical measurements indicate that ~25% of the mass in the universe is made of dark matter, particles which have never been observed on earth. I am working on direct detection of dark matter, via dark matter particle-nucleus scattering, shown above, in a terrestrial laboratory. My work focuses on distinguishing neutron backgrounds from dark matter signals in liquid Argon dark matter detectors, and on detecting the direction of the dark matter particles, which is potentially a powerful discriminator between a dark matter signal and terrestrial backgrounds.
