The NanoBio Lab focuses on the fundamentals, implications, and technological applications of biological electron transport, using environmental microbes as model systems. This is a highly interdisciplinary area, drawing from the toolboxes of nanoscience, condensed matter physics, electrochemistry, and environmental microbiology. In contrast to solid state systems (e.g. metals and semiconductors), where the mechanisms of charge transfer are well understood, with immense technological consequences ranging from computers to solar cells, comparatively little is known about the physics of biological charge transfer, especially over long distances.
The research in this group examines the physics of the problem over large length scales and in the full biological context of microbial respiration and biotic-abiotic interactions. In addition to the basic science, we research renewable energy recovery in biological fuel cells, and develop new nanomaterials for energy conversion.
