Welcome to the Miyashiro Lab!

We seek to understand how bacteria adapt to a host environment. We study the mutualistic symbiosis established between the Hawaiian bobtail squid (Euprymna scolopes) and a bioluminescent bacterium (Vibrio fischeri). From within a dedicated structure called the light organ, populations of V. fischeri produce light that the squid uses to camouflage itself at night. We use microbial genetics, confocal microscopy, and biochemistry to explore bacterial gene regulation within this fascinating symbiosis.
