I am a Research Assistant Professor (Ecosystem and Geospatial Modeling) in the School of Natural Resources, University of Nebraska-Lincoln. My research focuses on using novel approaches (machine learning and process based ecosystem modeling) to examine the impacts of long term agricultural amendments on crop yields and soil organic carbon under a changing climate.
Previously, I was a Postdoctoral Fellow at the Woodwell Climate Research Center with the focus improving the ability of earth system models to simulate soil carbon dynamics in the NIFA-USDA funded project "Soil Carbon Cycle Science in the Big Data Era". The primary objective of the project is to build an open-source spectroscopy-based system for rapid prediction of soil properties and then to use the predicted soil properties to improve soil carbon representation in global change models. Currently, we are using the daily version of the Century (DAYCENT) to test how using different soil properties (exchangeable of calcium and iron) can help to improve estimates of SOC change over time under future climate change and land use scenarios using the US Great Plains as a case study. My other research interests include understanding the response of terrestrial ecosystem to changes in multiple environmental factors. During my PhD in Auburn University, I developed a grazing module in the Dynamic Land Ecosystem Model to understand the response of grassland ecosystems to climate change and grazing across arid and semi-arid environments. Likewise, I have quantified the impacts of grazing and livestock production on greenhouse gas balance (CO2, N2O and CH4) during the course of 20th and early 21st century.
