Research of the Xu Group has two main thrusts: biomedical imaging and fiber optics. We are exploring new concepts and techniques for in vivo imaging deep into scattering biological specimens, such as mouse brain. We are developing new medical endoscopes for non-invasive real-time diagnostics of tissues without any exogenous contrast agent. We are developing novel optical fibers and fiber-based devices for biomedical imaging and optical communications.

Imaging Brain Structure And Function
We develop new optical techniques that enable deep, fast, non-invasive imaging of live mouse brains. We create unique, miniature optical devices for clinical applications, such as early cancer detection, real-time biopsy, and intra-operative surgical margin assessment. Leveraging state-of-the-art telecom technology, we invent new optical fibers and fiber-based device s for biomedical imaging in collaboration with our industry partners. The close integration and cross fertilization of biomedical imaging and fiber optics take full advantage of our broad interdisciplinary expertise, and enable us to be a leader in the field of optical imaging.
