I investigate the biogeochemistry of dissolved organic matter (DOM) across the land–ocean continuum. Using molecular biomarkers and ultrahigh-resolution mass spectrometry (FT-ICR MS), I trace the sources, transformations, and fate of DOM from estuaries to the deep ocean. My work links environmental gradients and microbial processes to DOM reactivity, including thermogenic and petroleum-derived compounds.

Current themes
- Estuaries and river plumes: sources, mixing, and transformation of DOM.
- Hydrothermal systems and natural petroleum seeps: production and alteration of refractory DOM.
- Oxygen gradients and water masses: preservation vs. turnover from surface to abyss.
- DOM–metal interactions and particle dynamics: mechanisms controlling export and sequestration.
- Coastal carbon storage: stability and vulnerability under environmental change.
Projects
- Amazon – GEOTRACES: Interactions of trace metals, DOM, and particles in the Amazon estuary and plume as key processes for fluxes into the Atlantic.
