Summary:

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.

Summary:

Ham's group builds CMOS integrated-circuit platforms spanning scalable, chip-based NMR spectrometers (including impedance-tuned microwave loops for controlling dense NV-diamond spin ensembles, developed with Ronald Walsworth) and CMOS intracellular microelectrode arrays that record from thousands of neurons in parallel — a dual quantum-sensing/bioelectronic-sensing program built around scaling sensitive spin- and electrode-based sensors onto integrated circuits.
