RESEARCH INTERESTS

  • Plant water relations and use
  • Plant nutrient relations
  • Stable isotope ecology
  • Plant physiological responses to episodic disturbance

Personal Statement

My research revolves around the interaction between global change processes, biogeochemical cycles and plant ecophysiology in desert ecosystems (including those in urban, riparian and upland areas). Specific questions I seek to answer include understanding 1) relationships between insect herbivory, resource allocation, and plant mortality, 2) how climate and soil texture interact to underpin the population structure, productivity and distribution of desert plant species and 3) relationships between anthropogenic nitrogen addition (through atmospheric nitrogen deposition, stream inorganic nitrogen loading, etc) and the invasion of non-native plants in desert ecosystems. To this end, I am applying stable isotopic methods, dendrochronological techniques, measurements of plant water relations and measurements in nutrient dynamics to improve our understanding of how desert plant systems function at multiple scales.
