“How inappropriate to call this planet Earth when it is quite clearly Ocean.
ARTHUR C. CLARKE
A Bit About The Team
I started the Marine Symbiomes Research Group at the Stazione Zoologica Anton Dohrn – National Institute of Marine Biology, Ecology, and Biotechnology in 2017.
We’re a curious and hardworking team, passionate about exploring marine symbioses in a fun and collaborative environment. We believe that everyone—regardless of age, career stage, or background—can bring valuable insights to our research. Science has no borders, and we love connecting with colleagues across Europe and beyond to tackle exciting questions together.
I’m always happy to hear from motivated students and postdocs who are interested in joining the group. Funding is limited, but keep an eye on this page and the Stazione Zoologica Anton Dohrn website for job openings. If you’re thinking about applying, feel free to reach out first! I’m also happy to support candidates who want to develop and apply for their own research grants.
Meet The People
Tamara Smith
PhD Student
I study microbial interactions in seagrass ecosystems and their role in biogeochemical cycling and carbon dynamics. I also enjoy the sea, reading, and socializing.
Germán Zapata Hernández
Postdoctoral fellow
I study benthic marine food webs and wildfire impacts. Experienced beekeeper working on climate change effects on Chilean beekeeping. I enjoy music, friends, and cold beers.
Maira Maselli
Postdoctoral Fellow
I got into symbiosis through mixotrophy in planktonic protists and now study carbon and nitrogen fixation in coastal waters. Research taught me to think big while minding the details.

Laura Dennis
Intern
Laura joined us for an internship, assisting with field and lab work. Last we checked, she was completing the IMBRSea Master Program.
Elisa Guarcini
Bachelor Student
Elisa completed her BSc thesis with us, contributing to the INBREATH project. Last we checked, she was seeking MSc opportunities abroad.
Our recent study in Communications Biology shows that Posidonia oceanica leaves exhibit complete nitrogen cycling, with key transformations accelerating under ocean acidification. These microbial interactions are crucial for seagrass resilience in a changing ocean.
In our New Phytologist commentary, co-authored with Sairah Malkin, we discuss Scholz et al. (2021), who reveal the widespread association between aquatic plant rhizospheres and cable bacteria, highlighting their ecological significance.
In our Frontiers in Microbiology paper, we investigated how zebra mussels influence nitrogen processes, focusing on the role of their microbiome at the ecosystem scale. Our findings highlight their impact on nitrogen cycling and reveal, for the first time, their contribution to dinitrogen fixation.
