Research:
Complex networks of organic and inorganic chemical reactions are critical to the cycling of carbon, nitrogen, sulfur and other materials through the atmosphere. When anthropogenic emissions of hydrocarbons, nitrogen oxides and other compounds perturb these reaction networks, undesirable levels of toxic or reactive species can be formed. The goals of our research program are to develop a better understanding of these atmospheric reaction networks and to characterize the chemistry t hat leads to poor air quality in urban areas, particularly in the State of Texas.

Research:
Banner's research and teaching interests center on Earth surface processes with the goal of understanding the interactions that occur between the atmosphere-land-ocean systems, and how these interactions are preserved in the geologic record. Avenues of investigation include the origin and evolution of carbonate rocks, groundwater, surface water, and the oceans. These subjects are explored using a range of approaches that include field studies, petrography, isotope and trace element geochemistry, geochronology, and modeling. Examples of research projects using these approaches are studies of cave deposits as records of the links between climate change and hydrology, studies of carbonate rocks as records of the chemistry of ancient oceans, and studies of modern aquifers in urbanizing environments.
