Research Interests

Marine invertebrates and their life-history stages live in intimate contact with the environment that includes the microbial world. My long-term research goals are to provide an understanding the functional interplay between the reproductive and developmental stages of marine invertebrates and symbiotic microorganisms, and how these partnerships evolve and are crucial life in the plankton. To do this I combine regular field-based experiments that simulates the oceanographic conditions and employ modern molecular biology and -omic techniques. This integrated approach has allowed myself and colleagues to find clear links between larval development, phenotypic plasticity, and life-history evolution with specific symbiotic microorganisms. We are currently testing hypotheses for a functional interplay between larvae and their symbionts in both sponges and echinoderms.
