present

Marie Curie Postdoctoral Fellow. Stanford University (USA) -University of Leeds (U.K.)

I am using multi-isotope proxies (d^44/40Ca, d²⁶Mg, d^238/235U, d^98/95Mo, d^34/32S, d⁸⁸Sr/⁸⁶Sr) in carbonates and black shales to investigate the effects of past ocean acidification and deoxygenation during periods of high atmospheric pCO₂ and biologic crises and diversifications; i.e. Permian-Triassic and Ediacaran-Silurian.

2011- present

Assistant professor in Geology. Universidad de Caldas, Manizales Colombia.

I am teaching curses in stable isotope geochemistry, environmental geology, carbonate sedimentology and geochemistry, field geology.

2010-2011

Postdoctoral Fellow. Smithsonian Tropical Research Institute, USA-Panama.

I applied sequence stratigraphic, chemostratigraphy (Sr-, C- and O- isotopes) and carbonate U-Pb geochronology to establish the timing of environmental and climatic controls on Cenozoic Caribbean carbonates deposition.
