RESEARCH INTERESTS:

I am interested in the natural beneficial interactions between bacteria and hosts, and how these interactions contribute to the health and development of the host.  My current research focus is to better understand the role of bacterial respiratory pathways in host-microbe relationships using genetic approaches.  The model system I use for these studies is the light organ symbiosis between the bacterium Vibrio fischeri and the Hawaiian bobtail squid Euprymna scolopes.
