Boeser works on neutrino astronomy and neutrino properties with the IceCube observatory at the South Pole, including optical-module instrumentation and calibration, ice-optics characterization, and oscillation/sterile-neutrino analyses; the group is also involved in next-generation radio and optical detection concepts. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), the relevance is instrumental rather than quantum-mechanical: photodetection, timing at ns level, and calibration of a km^3-scale detector. Included as an astronomy/astrophysics pivot where the sensor is the experiment.
