Research
The microbiome is the collection of all microorganisms that inhabit a defined environment. Our lab applies a variety of techniques, including high-throughput sequencing approaches, to understand how the manipulation of environmental microbiomes affects soil function and plant growth.
In particular, we are interested in:
- The impacts of unintentional human modification of microbiomes on the function of agricultural and ecological systems.
- The extent to which microbiomes can be purposefully modified in different biotic and abiotic contexts.
- Competition between complex microbial assemblages.
