Research Statement

I am an ecosystems ecologist with roots in mechanistic plant physiology. For two decades, I have striven to understand controls over dynamic interactions among plants, microbes, and soils, particularly in the fundamental terrestrial commodities exchange -- the rhizosphere. In the rhizosphere, organic carbon (from plants) fuels recycling of mineral nutrients (by microbes), maintaining the productivity on which ecosystems and humanity depend. My work combines organismal, hydrologic, soil physical, and ecosystems perspectives and aims to identify commonalities across systems in how organism-initiated flow (of water) and physical (soil) structure constrain, and promote, resource exchange. Such commonalities should extend to any system where interacting macro- and microorganisms (microbiomes) are embedded in, evolving in, and creating or shaping their complex physical environment. I also have particular interest in desiccation tolerance and photoprotective mechanisms among desert-dwelling, unicellular green algae, as a window into adaptations enabling the leap of diverse green plants from aquatic habitats to land. My work is interdisciplinary and collaborative, combining development of genetically engineered microbiosensors, chlorophyll fluorescence and gas exchange, in situ imaging,”omics” approaches and new stable isotope techniques, with organismal- and ecosystems-scale modeling.
