Plants can only function on land by virtue of beautifully efficient systems that regulate water transport and evaporation. My research focuses on how water transport and water use have evolved together in plants. The fundamental questions my research addresses are
- How do characteristics of the plant vascular system limit productivity?
- How does xylem and stomatal behaviour limit survival and distribution of plant species?
- How have the performance of hydraulic and stomatal systems changed through evolutionary time?
- How do hydraulic characteristics determine species ecology?
** Developing answers to these questions provides critical knowledge for diverse applications, ranging from understanding the impacts of past and future climate change, to developing more productive crop varieties.
