By exploring the properties of light, tissue, and their interactions, our laboratory invented, discovered or pioneered optical microangiography, full-range complex Fourier domain optical coherence tomography, optical clearing of biological tissue, elastic-wave sensing of elastic properties of tissue, phase-sensitive optical coherence vibrometry, multifunctional nanoparticle contrast agents and their applications in imaging tissue morphology, cerebral blood flow, retinal blood perfusion, cochlear blood perfusion, and embryonic heart development. The research topics currently active in the laboratory include:
