Plants are the interface between the atmosphere and the soil in most regions across the globe. Plants move water from the soil into the atmosphere while simultaneously converting atmospheric carbon dioxide into biomass that ultimately ends up in the soil. Plants change the conditions of the small area immediately surrounding them (microclimate). For example, tree canopies cool the underlying soil through shading or dark tree branches absorb more sunlight in the winter and melt the surrounding snow. These impacts can add up to affect the global climate over large scales. My research focuses on understanding how plants interact with their surrounding environment and how water cycling might ultimately affect plant growth from the plant to the global scale.
