Aerobic organisms share the threat of oxidative damage, since oxygen generates toxic byproducts through cellular respiration that damage proteins and DNA. We are trying to understand how cells adapt to both chronic and acute exposure to oxidants. In particular, we study the genetic responses to oxidative stress in organisms that can switch between aerobic and anaerobic lifestyles, including the bacterial species Escherichia coli and Geobacter sulfurreducens.
