Research Interests

My primary research interest as an ecologist has been the interaction between plants and soil microorganisms; especially mutualistic and associative soil organisms that live in the root zone of plants. Of special interest are mycorrhizal fungi that form mutually beneficial relationships with plant roots. Mycorrhizal fungi can enhance plant growth, disease resistance, drought tolerance, and affect plant community composition. These fungi can also influence other soil microbes that affect soil fertility through the cycling of nitrogen and phosphorous in natural systems. Consequently, mycorrhizal fungi may be key organisms in many communities, and a better understanding of how they interact with plants and other soil microbes is necessary for the future sound management of natural ecosystems. Our laboratory has two interrelated goals: 1) to describe the diversity of fungi in natural systems and to understand the environmental factors affecting this diversity 2) to understand the functional consequences of mycorrhizal diversity for plant growth, plant community structure, and ecosystem processes.  Our laboratory uses modern, DNA-based techniques for describing soil micro-organisms including mycorrhizal fungi.
