Community ecology of microbiomes

We apply ecological principles and theoretical frameworks to understand the structure and funciton of host-associated microbiomes, focusing on the human gut microbiome. We are also interested in how global environmental change affects the human gut microbiome. Here are some of our publications:

Resource competition and host feedbacks underlie regime shifts in gut microbiota

Microbial cross-feeding promotes multiple stable states and species coexistence, but also susceptibility to cheaters
