Research Interests

I am interested in developing tools for biologists and doctors. One specific area of interest is in the development of techniques that break the “optical diffusion limit” due to light scattering, for achieving light focusing and optical imaging deep inside biological tissue. During my PhD training in Prof. Lihong V. Wang’s group, we developed/improved optical phase conjugation based wavefront shaping techniques, including time-reversed ultrasonically encoded (TRUE) optical focusing and time-reversed adapted perturbation (TRAP) optical focusing. These techniques are used to focus light deep inside biological tissue, for noninvasive high-resolution optical imaging, manipulation, and therapy. I have also done research in photoacoustic imaging, ultrasound-modulated optical tomography/acousto-optic imaging, and fluorescence imaging.
