Research Interests

My research is directed at understanding the molecular basis of NADPH oxidase inhibition by apocynin (4-hydroxy-3-methoxyacetophenone). The activated NADPH oxidase complex produces reactive oxygen species which are involved in the early stage development of a series of inflammatory diseases such as atherosclerosis, diabetic retinopathy and asthma. A clearer understanding of this inhibition mechanism may lead to a novel therapy for diseases involving NADPH oxidase induced oxidative stress.
