Research interests
Multidisciplinary approaches to the biology and ecology of marine invertebrates as it relates to their susceptibility to anthropogenic impacts and climate change. Specific research lines include:

  • Invasive ecology of introduced ascidians
    • Species identification and barcoding
    • Population connectivity and phylogeography
    • Life cycle characterization
  • Stability and significance of symbiotic microbial communities in sponges and ascidians
    • Biodiversity and specificity
    • Symbiont stability and host resilience
    • Secondary metabolite production and ecological significance

Background information

  • Ascidians and sponges are filter-feeding organisms with an abundance and diversity of species and functions that render them critical to healthy ecosystem functioning
    • Sponges provide refuge for many small invertebrates and are critical to benthic-pelagic coupling
    • Ascidians are important fouling organisms, sometimes becoming invasive and disrupting the organization of the local benthic community
  • Sponges and ascidians commonly host diverse and dense autotrophic and heterotrophic bacterial communities as well as archaeal symbionts
    • The consequences of harboring symbiotic microbes may range from increased holobiont susceptibility to enhanced adaptive capacity and resilience of the host
    • Pharmaceutically interesting secondary metabolites are produced by sponge and ascidian holobionts as a defense mechanism against predation, competition and fouling
