Research Interests

I am interested in developing techniques for deep-tissue optical focusing and imaging. During my PhD study in Prof. Lihong V. Wang’s group, I developed optical phase conjugation based wavefront shaping techniques, including time-reversed ultrasonically encoded (TRUE) optical focusing and time-reversed adapted perturbation (TRAP) optical focusing, to focus light deep inside biological tissue for noninvasive high-resolution imaging, optical manipulation, and phototherapy. I also had experience in photoacoustic imaging, ultrasound-modulated optical tomography/acousto-optic imaging, and fluorescence imaging.
