The transfer of electrons to current harvesting electrodes by the Geobacter sulfurreducens is the primary focus of my research. Determining the electron transport chain to outside the cell during electricity production will allow for the optimization of the process and better fuel cell performance. We are currently exploring biofilm structure and conductivity, analysis of mutants in electron transport proteins, testing of electrode materials and fuel cell design. The tools currently being used to explore these questions include microarrays, proteomics, confocal laser scanning microscopy, electrochemical, protein and metabolite analyses.
