Research Interests

My research is focused on investigating how vegetation processes affect water flow dynamics and pathways in soil and streams, and conversely, how water flow paths affect vegetation function in mountainous terrain. The ultimate goal is to improve our knowledge of how changes in land-use and/or climate will affect water resources and ecosystems. This interdisciplinary research uses state-of-the-art techniques to reveal patterns and processes at scales ranging from the leaf to the watershed. Some current topics include: evapo-transpiration partitioning using stable isotopes; impact of bark beetle outbreaks on forest water yield in southern Wyoming; and examining the influence of micro-climate on tree function using stable isotope analysis of tree rings
