Shapiro's group creates genetically encoded reporters and actuators for ultrasound and MRI - notably gas-vesicle acoustic proteins - and technologies for sonogenetic and magnetogenetic control, enabling noninvasive, deep-tissue molecular imaging and cellular control of engineered cells and neural circuits. Actively recruiting. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/âHz sensitivity.
