My current research focuses on understanding 1) how red algae do so much (motile spores, cytokinesis, growth) with such a reduced cytoskeleton, 2) how to make macroalgal aquaculture stronger by further developing and encouraging Alaria aquaculture, integrated multitrophic aquaculture, and finding solutions for common pests in nurseries, and 3) the structure of macroalgal-associated microbiomes of foundation species such as Fucus vesiculosus in the North Atlantic intertidal zone. I frequently conduct studies of the reproductive biology of macroalgae, herbivory, and non-indigenous species.
