Research Interests

I'm a Biogeographer, which means my science sits at that exciting nexus of understanding how external forces (like environmental and human factors) and internal characteristics (like leaf biochemistry and plant functional type) act as determinants of where species can live and thrive. 

The Barron-Gafford research group studies the interactive effects of vegetation and climate change on plant & ecosystem function to inform forecasting and decision makers. We tackle questions related to fields of Biogeography, Plant Ecophysiology, Ecosystem Ecology, Ecohydrology, and Critical Zone Science. We study how semiarid plants and ecosystems respond to threats from drought, climate change, and human pressures like over grazing or clearing for renewable energy production.

As a group, we are Biogeographers
We study the distribution of species and ecosystems across geographic space and through geologic time. To understand historic, current, and future distributions, you have to know about the climate, the sensitivities of  organisms to environmental stressors, how efficiently each uses resources, and how the species interact with one another.

We are Ecologists and Plant Physiologists

We examine these interactions among organisms and their environment, working across the soil-plant-atmosphere continuum.

We are Ecosystem Scientists
We make use of multi-scale approaches to quantify patterns of carbon & water flux in space and time using a suite of traditional and new technologies.
