The Boyd lab is interested in understanding the mechanisms by which the mammalian pathogenic bacterium Staphylococcus aureus survives in infection settings, as well as discovering new methodologies and technologies to prevent or treat infections. We primarily focus our attention on the processes of metal ion homeostasis and the transitions between growth in the presence and absence of oxygen. Since these operations are essential for successful S. aureus infection, we hypothesize that the knowledge gained from understanding the genetic and biochemical underpinnings of these processes can be used to improve infection outcomes.
