Current Research Interests
I am interested in improving our understanding of the dynamic interactions occurring between the Earth's surface and the atmosphere relating to climate change. These systems are closely coupled and require a multidisciplinary approach to fully appreciate their complexity. I am particularly interested in how greenhouse gas emissions and nutrient cycles are effected by land-use change and other anthropogenic drivers and the associated feedbacks from these forcings.
My dissertation focuses on:
- Reconciling N2O emission budgets using stream order scaling
- Understanding the spatial uncertainty in field-scale agricultural N2O fluxes using a remote sensing and geostatistical modeling approach
- Estimating the effects of a leguminous companion crop on agricultural N2O loss as a N2O mitigation tool
- Predicting the effects of climactic change on N2O emissions using large climate-controlled mesocosms
- Constraining the key drivers of aquatic N2O flux to identify "hotspots" and improve the spatial resolution of N2O emissions using geostatistical models.
