I am an ecologist and evolutionary biologist interested in plant-microbiome relationships. My work combines large-scale observations, mechanistic experiments, and molecular approaches to explore the ways in which plants interact with their associated microbes, how these interactions vary under different conditions, and what impact they have on the ecology and evolution of populations, communities, and ecosystems.
I am currently the Lead Data Scientist at the Society for the Protection of Underground Networks (SPUN). I was previously a postdoc in the Peay Lab at Stanford University working on the biogeography of fungal symbioses and how they influence plant host distributions, species coexistence, and ecosystem functioning. I completed my PhD in the Schweitzer Lab at the University of Tennessee where I focused on the eco-evolutionary dynamics of plant-soil linkages and their response to global change.
Research
Microbial drivers of diversity and function
Plants assemble, defend themselves from, and form symbioses with highly diverse microbial communities. These relationships affect individual plant performance, influence population dynamics that shape community composition, and help determine the productivity and biogeochemical cycles of entire ecosystems. My research explores the plant-microbe interactions behind patterns of biodiversity and ecosystem function.
Community and ecosystem genetics
Plants alter soil properties and communities through functional traits that can be heritable and evolve along selective gradients. As a result, the ecology of plant-soil interactions can be tied to their evolutionary processes, and vice versa. I study how these types of eco-evolutionary dynamics play out in plant-soil-microbial linkages, and how environmental change will alter the connections between genes, communities, and ecosystems.
Plant-soil linkages and global change
Plants might adapt to increasingly stressful climates, persist via phenotypic plasticity, or shift their distributions to remain within their climatic niche. Under these scenarios, interactions between plants and their microbial communities are likely to mediate fitness responses, the expression of certain phenotypes, and future range limits. One of my primary research goals is to advance understanding of how plant responses to global change are mediated by the diversity and functioning of their microbiome.

Our latest work showing how plants select soil microbial communities that direct the timing of their spring leaf emergence is now out in New Phytologist and Communications Biology. These two projects provide new details on the role that soil microbiome variation plays in mediating an important plant phenotypic response to climate change, and would not have been possible without the support of many undergraduate researchers helping with thousands of phenology measurements!

I presented in the FEMS Microbiology Ecology Webinar series on our recently published study measuring how forest soil microbial diversity and function respond to experimental warming. This work was done in collaboration with researchers at the Boreal Forest Warming at an Ecotone in Danger experiment (B4WarmED) in northern Minnesota.
