Curriculum Vitae

 

Research Interests

Symbioses with microorganisms play an essential role in the health and physiology of diverse marine organisms. However, environmental stressors such as climate change increasingly threaten the physiological function of the metaorganism (the assemblage of all participants in the symbiosis, forming an ecological unit). My research investigates the biogeochemistry of host-microbe interactions, as well as the physiological and ecological consequences of these dynamics. I am mainly interested in the carbon and nitrogen cycles and I focused so far on the physiology of two different model systems: the photosynthetic coral symbiosis, and the chemosynthetic lucinid clam symbiosis. A key goal of my work is to provide a mechanistic understanding of how host-microbe interactions lead to peculiar metabolisms of the metaorganism, and of how these contribute to nutrient cycling and ecosystem functioning. I use a combination of underwater fieldwork for sample collection and incubation experiments with living organisms. Nutrient and oxygen measurements, acetylene reduction assays and stable isotope probing are used to quantify fluxes. I perform manipulation and mesocosms experiments to disentangle the role of environmental conditions in shaping the functioning of the metaorganism. By integrating across biological scales and maintaining an environmental context, my work will help determine the capacity of symbiotic marine organisms to shape their ecosystems and to withstand and adapt to a changing marine environment.
