We are interested in how microbes cycle nutrients and contaminants in the environment through redox chemistry and precipitation reactions. Current focus is on understanding transformation mechanisms of nitrogen compounds and biomineralization processes.
Current Projects
Biological Templation of Carbonate Minerals
Organisms utilize organic and inorganic components to control the phase and morphology of carbonate biominerals.
