Biography

Professor Wang's research focuses on biomedical imaging. His lab has developed photoacoustic imaging, which allows for noninvasive observation of biological tissues. Compared to conventional optical microscopy, these techniques increase penetration by orders of magnitude, breaking through the optical diffusion limit. Wang's lab has invented functional photoacoustic tomography and 3D photoacoustic microscopy, as well as several other significant imaging techniques. These advancements contribute broadly to early cancer detection, surgical guidance, and brain imaging. Professor Wang's research extends to quantum physics and quantum imaging, where entangled photons exhibit nonclassical correlations that enhance imaging capabilities. His work bridges atomic physics and quantum research, exploring the fundamental aspects of photon behavior and quantum interfaces. His Monte Carlo model for photon transport in scattering media is widely regarded as a standard tool in the field. He has a rich academic background with degrees from Huazhong University of Science and Technology and Rice University, and has held various esteemed positions since joining Caltech.
