I am a microbial ecologist. My research addresses the responses of natural bacterial communities to physical, chemical, and biological environmental variables. My group examines the relationship between microbial diversity and ecological function, and seeks to answer a number of specific questions at the level of ecophysiology, population dynamics and community ecology. To facilitate this work we focus on specific groups of bacteria that directly contribute to a particular function, such as the diazotrophic bacteria, the sulfate reducing bacteria, and the acetogenic bacteria. Pathogenesis is another ecological function of interest and current research examines pathogenesis of marine Vibrio species and the specific virulence mechanisms employed by Vibrio parahaemolyticus.
Questions addressed in my research:
What is(are) the relationship(s) between microbial diversity and ecological function?
Are species richness and evenness of microbial communities in structured environments governed more by negative interactions of organisms or by positive interactions?
What is the role of refugia in development of large populations of bacterial species?
How do mechanisms contributing to pathogenesis evolve in natural bacterial populations?
