Research description:

My main research interests centers around the intersection of plant and microbial community ecology. How can traditional ecological theories of community assembly and species interactions be used to gain insight into microbiome formation, evolution, and impact on diverse host species? I primarily study the fungal colonizers of aboveground leaf tissues in diverse plant hosts, ranging from tallgrass species of the N. American Midwest to herbaceous plants from the Asteraceae family. Known as fungal endophytes (‘inside plant’), these symbionts are increasingly recognized for their functional roles in altering host physiology and immune system defense. However, many questions surrounding their dispersal and host-impact
remain poorly understood. What are the consequences of colonization for host fitness and competition in natural systems? How can we use community phylogenetics to better understand the interactions and evolution of microbiomes across multi-host plant communities? I am also broadly interested in the evolution and maintenance of symbioses and parasitism in host-microbial interactions.
