INSITE Director
Dr. Nishiguchi is an evolutionary biologist and microbial ecologist who is interested in the evolution of animal-microbial interactions with respect to their environment. Her laboratory studies the mutualistic association between sepiolid squids (Mollusca: Cephalopoda) and their Vibrio symbionts which provides a versatile and experimentally tractable model system to study the population dynamics and cospeciation between bacterial species and their diversity among host squids.
Researchers in Dr. Nish's laboratory focus on aspects of molecular signaling, population genetics of Vibrio bacteria, molecular specificity of symbiosis genes, competitive exclusion of non-native symbionts, phylogenetic relationships among squids in the family Sepiolidae, as well as modeling certain aspects of the ecology of the association.
