Overview
I have an interest in exploring better medical and surgical ways to treat patients and will continue to be involved in clinical trials involving novel drug-delivery systems and new surgical procedures. I also have a research interest in the differential burden of glaucoma on African-derived populations. This question is multi-faceted, and involves a comprehensive evaluation of the genetics, economics, accessibility to treatment, and response to therapy of these populations.
