I am ecosystem scientist who works at the interface of ecology, earth system science and land use planning studying the processes shaping watersheds and their responses to anthropogenic changes. From this foundation, I tackle the challenges and complexities of sustainability and global change science.

My research program is highly interdisciplinary and bridges diverse aspects of environmental science, largely from an ecosystems perspective. Much of my work lies within the mission of unraveling competing and interrelated processes in water-limited ecosystems within the grassland-forest continuum, gradients of woody plant coverage that include shrublands, savannas, and woodlands, as well as grasslands and forests. I am interested in interactions between woody and herbaceous plants and the associated patterns of canopy patches of woody plants and the intercanopy patches that separate them.

The main objective of my research group is to characterize key aspects of vegetation that govern water, energy, and carbon cycling in water-limited ecosystems, and vice versa. Understanding these cycles is critical to the sustainability of our native ecosystems as we anticipate gradual and abrupt climatic and anthropogenic change. This understanding is fundamental as changes in our native ecosystems will undoubtedly have effects on the health of our watersheds and rivers. We use state of the art field, lab, and modeling techniques to
