Expertise: Host-microbial interactions, Octocoral symbioses, Metagenomics & Genomics, Metabolomics, Experimental Biology
Short Bio:
Tina Keller-Costa is a Research Scientist and Invited Assistant Professor at Instituto Superior Técnico. She studied Biology at the Friedrich-Schiller University of Jena (DE) and wrote her master's thesis on the freshwater sponge microbiome at the University of Groningen (NL). She holds a Ph.D. in Biology from the University of Évora and the Centre of Marine Sciences in Faro, where she identified the male pheromone of tilapia in collaboration with the Max Planck Institute for Chemical Ecology, Jena. Tina's current research focuses on the molecular mechanisms of marine host-microbial interactions; the response of the octocoral holobiont to climate change; and the sustainable use of marine resources, particularly chitinases.
