Research Summary

  • Costello's research interests include systems sustainability, specifically the evaluation of greenhouse gas emissions, nutrient flows, water and land use associated with current and potential agricultural systems and management options.
  • Costello uses life cycle assessment and fate and transport models to link land-based anthropogenic activities to impacts incurred by ecosystems. She is particularly focused on food consumption and the role of human behavior as a driver for agricultural production. Specifically, she uses environmentally-extended input-output life cycle assessment (EE-IO LCA) techniques to evaluate environmental impacts throughout production supply chains the U.S. economy.
  • She also evaluates biofuels at the systems level using sustainability metrics, e.g., greenhouse gas emissions, nutrient pollution. Similarly she models how biofuel co-products, e.g., distiller’s grains, impact livestock and human feed/food production and supply chains.
