Nvestigating the effects of past changes in environmental conditions on the global marine biogeochemical cycles using non-traditional stable isotopes (Ca, Mo, U, Mg, Sr)
Investigating how past changes in carbonate factories paralleled major fluctuations in climate and ocean chemistry during periods of high atmospheric pCO2 (Neoproterozoic, Permian-Triassic, Cretaceous OAEs, Paleogene)
Modeling the evolution of marine sedimentary basins along the Circum Caribbean using multi-proxies ; i.e., sequence stratigraphy, detrital zircons U-Pb dating, carbonate U-Pb dating and C, Sr isotope chemostratigraphy.
Evolution of Cenozoic continental sedimentary basins along Northern South America using sequence stratigraphy, detrital zircons U-Pb dating, petrography and heavy mineral analysis.
Investigating Holocene climate variability using multi-isotope and multi elemental techniques in speleothems and lakes.
