I seek to improve our understanding of crop carbon and water exchange from field to global scales. I answer my research questions with models that capture the spatio-temporal dynamics of agricultural production (area × yield) and evapotranspiration. The models are: (i) implemented in a Geographic Information System; (ii) based on principles of light-use efficiency and machine-learning; and (iii) driven by Earth observation, climate reanalysis, and other geospatial information. The work flow reduces uncertainties in crop models and improves agricultural monitoring systems, as well as motivates my teaching and capacity-building activities. The long-term impact of my work is increased agricultural production, enhanced resilience of crops to drought and other climate shocks, and reduced CO2 emissions caused by agricultural expansion into natural ecosystems. Such outcomes help achieve Sustainable Development Goal SDG-2 (“Zero Hunger”), SDG-6 (“Clean Water and Sanitation”), SDG-13 (“Climate Action”), and SDG-15 (“Life on Land”).

Research profiles

I grew up in the Mojave Desert where a few spectacular weeks a year a wanderer’s senses are stimulated by the unique smells of thirst-quenched soil and sudden wildflower blooms. These early experiences and my exposure to amazing educators influenced me profoundly. Consequently, I am driven to understand how we impact our environment and to help students discover their own passion in this regard.
