Microbial life in hydrothermal plumes and in the far-field

My PhD project integrates molecular biology, thermodynamics, and oceanographic data to model how hydrothermal vents shape microbial communities along the mixing gradient from fluid discharge to the neutrally buoyant plume. Utilizing public databases and culture-independent multi-omic tools, I contrast near-field communities—fueled by high-flux gases (H2S, H2) and heavily enriched metal environments—with far-field communities that, while depleted in trace metals, are still influenced by highly diluted hydrothermal fluids. My research focuses on the Kairei, Mid-Atlantic Ridge, and Aurora vent fields to determine how these communities drive the organic complexation and global distribution of trace iron. Finally, I aim to resolve the global biogeography of the Sulfurimonas pelagic clade, modeling the thermodynamic and energetic niches that differentiate specialized plume lineages from widespread non-plume lineages in the deep sea.
