Biography

Professor Wang's research focuses on biomedical imaging. In particular, his lab has developed photoacoustic imaging techniques that allow for noninvasive observation of biological tissues. Compared to conventional optical microscopy, these techniques provide increased penetration by orders of magnitude, effectively breaking the optical diffusion limit. The Wang lab has invented functional photoacoustic tomography, 3D photoacoustic microscopy, and photoacoustic Doppler effect imaging, among other innovations. His work spans a variety of applications including early cancer detection, surgical guidance, and brain imaging. The Monte Carlo model for photon transport in scattering media developed by Wang has become a worldwide standard tool in the field. His quantum research includes investigations into quantum entanglement, quantum imaging, and atomic physics. The properties of entangled photons allow for advanced imaging capabilities that surpass classical optics. In addition, he has developed theories that challenge traditional views of the Bloch equation and its relation to quantum mechanics. Wang's contributions to the field significantly enhance our understanding of both classical and quantum optics.
