We study social interactions in microbes and other group-living species

Organisms regularly meet members of their own and other species. Whenever these interactions affect survival and reproduction - the currencies of Darwin's natural selection - they are "social" in evolutionary terms. We study how social interactions affect and define biological systems. We study animals groups and interactions within genomes, including transposon evolution. But our primary focus is the microbes who commonly live in dense and diverse communities. And most recently, we have turned our attention to host-symbionts systems including the mammalian microbiome. Our work combines theory and experiments, and we write reviews of key concepts and debates in the study of social systems.

New piece in Nature: we argue that the classical approaches of evolutionary biology are needed to understand the human microbiome. Read the paper here. 

New piece in PNAS: we show how a cell's shape can be critical to its competitive ability with our new agent-based model, backed up by experiments. Read it here.
