Main Research Interests
My research focuses on characterizing the molecular and biochemical interactions between the environment, Eukaryotic hosts and their microbial communities. Hosts and their symbionts build complex chemical spaces that influence the function, survival and maintenance of their relationships. As such, my research seeks to describe and understand the role of specific partners in the consumption, production and regulation of small molecules, or metabolites.
I am currently developing and applying metabolite profiling methods for seawater samples in order to explore the influence of host-microbe associations on their environment. Using this novel approach, our unpublished work shows that globally, seagrasses modify their habitat by (1) producing and secreting sugars to their rhizospheres and (2) altering their associated sediment microbial communities (taxonomy and function) to favor beneficial taxa. From these data, we show that carbon sequestration - a key function of seagrass sediments- mediated by seagrasses is influenced by the symbiotic interaction between meadows and microbial communities populating the rhizosphere.
