Anders designs integrated-circuit quantum and magnetic-resonance sensors: EPR-on-a-chip (single-chip ESR spectrometers reaching ~1e9 spins/sqrt(Hz)), chip-scale NMR relaxometry for point-of-care, and CMOS/SiGe-integrated diamond NV magnetometers - miniaturizing spin sensing onto silicon. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is the integrated-circuit route to deployable NV/EPR ensemble sensing.
