Dr. Simkins’ research broadly focuses on past changes in coastal, marine, and glacial environments and the processes that control those changes, primarily using sedimentological and geomorphological archives. For more information and available graduate student positions, visit her research website.
My primary research interests are in the areas of (1) catchment hydrology, focusing on hydrological and geochemical transport processes, and (2) land-atmosphere interaction, including the exchange of water, energy, and gaseous compounds such as carbon dioxide, nitrous oxide, and methane between the terrestrial surface and the atmosphere. I seek to develop an integrated understanding of how the hydrological cycle, vegetation processes, and atmospheric dynamics are linked as well as how these connections are manifest in terms of nutrient cycling and ecosystem function.
My overall research interest is in watershed biogeochemical processes and identifying the hydrologic drivers of those processes. More specifically, my research focuses on the status and trends of stream flow and stream-water quality in response to stressors, including air pollution, climatic variability, and anthropogenic land-use influences.
My research focuses on the chemical quality of surface water and the geochemistry of sediments. Measures are sought for the amount and sources of anthropogenic inputs of both major elements and trace elements into freshwater catchments and estuarine and deltaic depositional sites. Interest has been devoted largely to river and estuarine systems of the temperature zone, but also includes tropical systems, especially in Southeast Asia.
