Yang's group integrates optics and computation for biomedical imaging - Fourier ptychographic and lensless coded-ptychography microscopy for high-resolution wide-field imaging, and wavefront-shaping/time-reversal methods to focus light through scattering tissue for deep-tissue imaging and transcranial sensing. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
