Research summary: 

Our work has contributed to a great change in perspective on the role and nature of reactive oxygen species (ROS) through: (1) our characterization of Hsp33, one of the first redox-regulated proteins identified, and an important player in the oxidative stress defense of bacteria, (2) the development of quantitative tools that have allowed us to identify redox-sensitive processes in bacteria and eukaryotes, and (3) the discovery of a link between early exposure to oxidants and aging.  The overall goal of my research program is to generate an integrated and system-wide view of the beneficial and deleterious effects of ROS. These studies have the clear potential to form the basis for the development of more powerful antimicrobials and novel antioxidant strategies.
