My background is primarily in the field of organic photovoltaics (OPV) or "plastic solar cells" for low-cost solar energy harvesting. My group at DU studies materials design, device physics, and overall device architecture for OPV in close collaboration with NREL and academic and industrial laboratories around the globe. My other interests include studying the dynamics of complex systems such as neuronal networks, protein interaction and metabolic networks, and ecological systems. My group is beginning to apply statistical physics techniques such as entropy analysis to help elucidate meaningful correlations and structure in such biological and natural systems. This work is done in close collaboration with members of the Eleanor Roosevelt Institute on the DU campus and also colleagues around the country. Please see my group homepage for further details.
