My work uses agricultural systems as a platform to explore scholarly questions about climate resilience, with the overarching goal of improving socio-economic justice and equity. My research can be categorized as studying food security, climate resilience, and nutrient management. My specific research aims are to reduce pollutants, including greenhouse gases, improve crop nutrition, store soil carbon, and increase water use efficiency.
