Research

My research interests center on nutritional- and stress- physiology of native and agriculturally relevant plants. More specifically, I am interested in how plants survive in areas that are typically hostile to most species. Aquatic plants, for example, often reside in submerged or flooded conditions where the substratum lacks oxygen and has redoxymorphic features that are typically stressful for most flowering plants. In coastal and marine systems, this stress is exacerbated by the presence of interstitial saline waters.  By characterizing the environmental limits and physiological adaptations to these otherwise harsh environments, we will be better able to design and reconstruct important natural systems.
