My research interest centers on development of cutting-edge and translational biophotonics technologies that interface and bridge basic engineering research and medical diagnosis and intervention. The research and training involves vertical integration of multiple disciplines, including (but not limited to) optics, electrical engineering, micro-nano technology, biology and clinical medicine. The ultimate goal of our research is to transform our capability of disease detection at early, manageable stages, monitoring therapeutic effects and treatment outcomes, and guiding interventions. The technologies also offer new opportunities for basic research in exploring new frontiers of disease mechanisms, brain function, bio-marker discovery and integrated diagnosis and therapy. Some specific research interests include:
- Optical Coherence Tomography (OCT)
- Multiphoton Endomicroscopy
- Label-free Mass-spectrometry Imaging (MSI)
- NIR Fluorescence Imaging
- Functional Nanocapsules and Nanoparticles for Molecular Imaging
- Noninvasive Cancer Detection, Infection and Inflammation Detection, Preterm Birth Assessment, Wound Healing Imaging and Surgical Guidance
- In vivo Cellular Metabolism Imaging, Brain Function Imaging
