Kelsey Oliver-Mallory is a postdoctoral research associate at Imperial College London leading an R&D effort to extend the scientific reach of xenon-based dark-matter detectors. She is also leading a subgroup of the XLZD consortium that is evaluating and optimizing the sensitivity of a next-generation detector to WIMPs, CE𝛎NS, and low-mass dark matter. She is a member of the LUX-ZEPLIN and LUX collaborations and has worked on optimizing the detectors to low-mass dark-matter candidates by using machine learning to discriminate against backgrounds that limit sensitivity in this regime. She previously earned her PhD from the University of California Berkeley where she worked on measurement and control of radiogenic backgrounds for such detectors.
