Research InterestsMy research interests are at the interface of ecology and evolutionary biology. The predominant theme within my research program is to understand the fundamental role of microbial symbiotic interactions on population processes and community assembly and structure. I study plant-microbe systems, with a particular focus on the ubiquitous but invisible fungal endophytes, which are fungi that live asymptomatically in plant tissues. Plant-microbe interactions have many important roles in terrestrial ecosystems, such as resource exchange, effects on plant traits, and modifying biotic interactions. My general areas of research include:
• microbial community ecology: fungal endophyte community composition, diversity, and structure
• ecology and evolution of symbiotic interactions: plant-microbe interactions, particularly grass-fungal interactions; effects of symbioses on host traits; pathogens in natural and agricultural systems
• plant ecology: ecology of clonal plants; the role of soil microbial feedbacks in plant communities
• molecular ecology: identification of microbes; molecular approaches to examine plant and fungal populations
I use an interdisciplinary approach in my research, drawing upon ecological, molecular, microbiological, physiological, and evolutionary methodologies. Results from my research will help us to understand the reciprocal influence that symbionts have on each other and the interplay between their populations and communities.
