Description: This thesis describes research I conducted within the XENON program of dark matter searches. In particular, I focus on contributions I made to the development of a novel system for purifying liquid xenon employed in XENONnT, to the reconstruction and modeling of electronic and nuclear recoil signals by fitting calibration data, and in the employment of these tools to world-leading physics searches for spin-dependent DM-nucleus scattering and coherent neutrino-nucleus scattering from boron-8 solar neutrinos.
