Overview


My research interests focus on studying the role of nitric oxide and related enzymes in the pathogenesis of lung disease, specifically that caused by nitrosative/oxidative stress. Proposed studies are performed in cell culture and applied to animal models of disease, then examined in human disease where relevant. It is our hope that by better understanding the role of NO and reactive nitrogen species in mediating inflammation, and regulating cell signaling, that we will not only help to unravel the basic mechanisms of NO related lung disease, but also provide a rationale for targeted therapeutic use of NO.


Key words: nitrosative defense, lung injury, nitric oxide
