How and why infections make us sick

Our goal is to understand the mechanistic basis of sickness as a host defense strategy.

We use tools from mucosal immunology and molecular neuroscience

to understand the neuroimmune interactions that lead to sickness, and how these interactions influence host and microbial fitness.

We are an interdisciplinary group of scientists

committed to rigorously and fearlessly pursuing fundamental questions about the biology of host defense.
