Micropaleontologist and paleoceanographer, CNRS postdoctoral researcher at CEREGE
specializing in late Neogene planktonic foraminifera.
I am a Colombian geologist, with a MSc in paleontology from Brazil,
and a PhD in geology from the Czech Republic. Currently I am a postdoctoral
researcher at ExoCean, CEREGE (France) supervised by
Dr. Thomas Chalk
and Dr. Sonia Chaabane
on the ERC StG ForCry.

Advanced training in planktonic and benthic foraminiferal taxonomy, stratigraphy, and biostratigraphy
Ten-day intensive course held in Kraków, combining ~40 hours of lectures and ~40 hours of practical microscope work. Training covered Paleozoic, Mesozoic, and Cenozoic planktonic and benthic foraminifera using thin sections, IODP/ODP materials, and petroleum-basin case studies. The program reviewed classification schemes, evolutionary history, and practical applications in biostratigraphy and paleoecology, with exercises following each module. A highly specialized course for students and professionals working with foraminifera.
From Greenhouse to Icehouse – The Cenozoic Arctic Ocean and Global Climate History
Two-week intensive training held at MARUM – Center for Marine Environmental Sciences and the IODP Bremen Core Repository, focusing on the long-term evolution of Arctic climate during the Cenozoic. The summer school combined expert lectures, core description, and IODP-standard analytical methods within a shipboard-simulation environment. A diverse and highly international cohort enabled strong scientific exchanges and long-lasting collaborations.
A breathtaking archaeological site & a geological treasure.
Visiting the pyramids was an unforgettable experience. Like everyone, I first looked up, amazed by their scale and beauty. But very quickly, the geologist in me took over: I began examining the limestone blocks, noticing large bioclasts, visible even without a microscope. The Pyramid limestones preserve shallow-marine carbonates including Nummulites (benthic foraminifera).
Paleozoic stratigraphy and fossil exploration in the Anti-Atlas region
Field excursion across key Paleozoic localities in Morocco, exploring expanded Paleozoic sequences and exceptionally preserved fossils. The trip provided hands-on experience with trilobites, crinoids, and diverse invertebrate assemblages, alongside sedimentological logging and paleoenvironmental interpretation in one of the most iconic Paleozoic regions of the world.
