Biographical Sketch

Dr. Xu has solid training in clinical ophthalmology and ocular pharmacology. His major research activities are in the fields of anti-cataract drug development and using eye diseases as models for aging and systemic metabolic diseases study:
    1. Naphthalene induced cataract model is used to mimic human age-related cataract and a new mechanism is thus proposed to explain the cataract formation. A few drugs tested for cataract therapy have showed positive outcome based on the new mechanism.
    2. The mechanism of diabetic retinopathy in animal model is studied and in this model a new phenomenon is disclosed that neuronal injury occurs as early as the damage to the vascular in retina is made. Based on this finding, several current clinical medicines have been retained and one of them has been confirmed with new function in prevention of DR when delivered in localization at early stage.
