Understanding how bacterial competition shapes the evolution, structure,

and function of marine microbial communities

LAB MISSION

Our research focuses on how interbacterial competition impacts community structure and function in marine ecosystems. Specifically, we aim to couple bacterial model systems with environmental culturing and field-based experiments to study how bacteria evolve and regulate deployment of competitive mechanisms. Connecting the molecular mechanisms of these behaviors to ecological roles will inform our understanding of how these social interactions affect community composition and influence animal and ecosystem health.

RESEARCH

The vibrio-squid symbiosis as a model for bacterial competition

How do naturally co-occurring bacterial populations compete for a host niche?

We are using Vibrio fischeri as a model for studying how genetically distinct bacterial strains compete for a limited number of host colonization site.
