Dr. Field studies how agricultural and engineered systems can contribute to climate change mitigation, carbon sequestration, and negative emissions. Originally trained in engineering, John joined the Paustian group at the CSU Natural Resource Ecology Laboratory (NREL) as a student in the Multidisciplinary Approaches to Sustainable Bioenergy NSF IGERT program, conducting dissertation research on bioenergy system lifecycle assessment. That work used the DayCent ecosystem model for bioenergy landscape design optimization, assessing where and how switchgrass could be grown to maximize climate benefits and minimize costs for a cellulosic biorefinery case study in southwestern Kansas. He also examined environmental–economic trade-offs in biochar production in the Colorado Front Range, and gasification of agricultural wastes for electricity production in Southeast Asia.
Today he serves at the project manager and an environmental sustainability team lead for the Bioenergy Alliance Network of the Rockies (BANR), a USDA-NIFA CAP consortium studying the viability and sustainability of utilizing beetle-killed wood as a feedstock for carbon-negative bioenergy production. He also leads two smaller projects studying the potential for cellulosic feedstock crop cultivation on marginal and abandoned cropland. He is particularly interested in interactions between bioenergy system scale and climate mitigation performance, as well as how natural and engineered climate solutions might optimally co-exist.
