ABOUT ME

ABOUT ME

My major research interest is the cycling of elements in the environment, especially the biogeochemistry of carbon. I aim to unravel the natural drivers that control marine ecosystems and the impact that anthropogenic factors have on them.

A major focus of my research is on the factors that regulate the downward flux of material from the surface of the ocean into the interior and from there to the seafloor. I study the role of particles in the oceanic carbon cycle using detailed geochemical characterization (bulk geochemical composition and stable isotopes, lipid biomarkers, major and trace elements, etc.).  I integrate the characterization of particle fluxes with the analysis of external (climatic) and internal (oceanographic) forcing conditions. I evaluate the impact of extreme weather events, such as hurricanes, on the oceanic carbon cycle.  I am also interested in the role of microbes in regulating carbon fluxes in the ocean.

I also have a significant interest in issues of direct societal concern, such as persistent organic pollutants and microplastics/nanoplastics in marine ecosystems, and the ways in which the oceans may be encouraged to remove anthropogenic carbon dioxide from the atmosphere.

When long time ago I read the sentence “...the sediments are the materials of the most stupendous snowfall the Earth has ever seen...“ (Rachael Carson, The Sea Around Us), my first thought was that I really wanted to know more about this snowfall, about its composition, transport, deposition, etc.
