Ordinary Academicians
My primary research interests are in biomedicine and biochemistry, focusing on the molecular basis of disease and aging in humans. In particular, I concentrated research efforts in the areas on oxidative and nitric oxide metabolism, mitochondrial function, post-translational modification of proteins and mechanisms of cell degeneration and death, with a discovery path that involves interdisciplinary approaches. My contributions have unraveled molecular mechanisms of chronic diseases and assisted to the design and development of therapeutics. Also, my work has contributed to understand oxidative cellular immune responses to invading pathogens and revealed the role of microbial antioxidant systems as virulence factors.
