Thesis research:

Over the past twenty years, Shewanella and Geobacter sp. have been studied for their ability to perform extracellular electron transfer (EET). This metabolism moves electrons from metabolism to terminal electron acceptors which are outside of the cell. This process allows for respiration of insoluble substrates such as iron, manganese, uranium and electrodes. Although there is still much to learn about these model systems, we do understand the general mechanisms for EET in Shewanella and Geobacter sp. This metabolism is not limited to Proteobacteria. It has been described in isolates from all over the tree of life in numerous extreme environments.
My thesis is to study microorganisms that have been reported to perform EET and characterize the mechanism of transport.
