Trophic interactions in deep-sea ecosystems

2018-01-01

Since September 2017, I’m a research scientist at the Deep Environment Laboratory of Ifremer Brittany, Brest, France. Ongoing projects include ecological plasticity of foundation species in cold seeps ecosystems, food web structure in hydrothermal vents from the Mid-Atlantic Ridge and Pacific back-arc basins, as well as trophic interactions in cold water coral reefs. I’m also building an open database for stable isotope ratios of deep-sea fauna.

More info on this research coming soon!
