Context matters: agathokakological roles for redox-active "antibiotics"

In this talk, Dr. Newman will explain what "agathokakological" means and how this word can help us understand the varied roles microbially-produced redox active metabolites play in diverse contexts, from the soil to chronic human infections.  These compounds, many of which are striking pigments that change color when they are oxidized or reduced, can serve as toxins or as lifelines for the cells that produce them according to their microenvironment and physiological state.  She will emphasize the importance of investigating their nuanced functions under environmentally-relevant conditions at the microscale, and discuss how we can harness our understanding of these molecules to develop new tools to control microbial populations and communities.
