Primary research interestes are in the determination of factors for the prevention, treatment, and control of global blinding diseases. Major areas of research have focused on the following three areas: 1. risk factors for cataracts, and disparities in access to cataract surgery survices,and eye care services in general; 2. Strategies for control of trachoma, with research on surgery, antibiotics, and envrionmental factors that can be used for trachoma control-reserch also on laboratory detection of chlamydial infection, and immunoloical factors associated with progression. 3. Impact of visual loss on function in older persons, especially older minority populations.
