Our research group studies plant-microbe interactions, urban soil ecology, and sustainable agroecosystem management. We integrate microbiome science, plant biology, and biogeochemistry to better understand the ecology of agricultural and managed landscapes and identify strategies that farmers and land stewards can implement to adapt to rapid environmental change. Below are some of the current projects our lab is working on.

The influence of microbial symbionts on crop traits: Plant-associated bacteria and fungi have a tremendous but understudied influence on crop growth. Through field, greenhouse, and laboratory experiments, we are currently working to understand how bacteria and fungi can regulate different plant traits and also influence the yield and quality of diverse crops.

Sustainable soil management strategies for urban farms and parklands: Urban greenspaces can offer a number of ecological, economic, and social benefits to communities across the globe. However, one of the largest challenges urban land stewards must contend with is building and maintaining healthy soils in the urban environment. Our lab is currently collaborating with a number of organizations in the San Francisco Bay Area to identify strategies we may implement to support soil health on urban farms and in regional parks.

Regenerative agroecosystem management: Our lab is currently collaborating with the Long-Term Agroecosystem Research Trial at the Kellogg Biological Station in Michigan to understand how diversified crop rotations can support soil biodiversity and nutrient cycling in agricultural landscapes. We are also interested in studying how other regenerative practices such as cover cropping and applying compost can support soil health and biodiversity.

Outreach and environmental education: Our lab is also passionate about science communication and partners with various groups to outreach our findings and science-based information to diverse audiences.
