My primary research interests are the documentation and study of Quaternary abrupt climatic changes registered in coastal and marine sediment cores using planktonic and benthic foraminifera, geochemical proxies, and time-series analyses. I work with marine sediment-cores from the Eastern Tropical Pacific, the Gulf of Mexico, and the Caribbean Sea, to reconstruct the changes in the surface ocean, marine productivity, oxygenation, subsurface denitrification, and intermediate circulation at different temporal scales: secular, millennial and glacial-interglacial. One of my project goals aims to reconstruct changes in atmospheric circulation linked to ocean circulation and to reconstruct connections between continental and oceanic zones. I am currently working on Holocene-Pleistocene paleoceanography in the NW Mexican Pacific and collaborating with projects in sandy beaches and coastal lagoons in the Gulf of Mexico and the Caribbean.
