Research Interests

Optics, imaging, and physiological markers

Development of a practical system for evaluation of oxygen saturation in the retina and optic nerve head using hyperspectral imaging, for eventual clinical application in the early diagnosis and monitoring of ocular vascular diseases in which the associated hypoxia could lead to loss of vision, including glaucoma, diabetic retinopathy, and age-related macular degeneration
