My most exciting current research work is probably a project that was started during a Working Group at NIMBioS in Tennessee, looking at how interactions between pathogens can be disentangled from survey data.

FEATURED PUBLICATION

Extending the theory about plant-soil feedback in the social network of trees. In a new study published in Nature Ecology & Evolution, researchers mathematically describe the social network that creates and maintains forest biodiversity. The paper presents a general equation that characterizes the interactions of any tree-microbe network, whether it consists of two or 2,000 species, by a single number. The work was the result of the activities of a NIMBioS Working Group, including two NIMBioS postdoctoral fellows and a sabbatical visitor.
