I am a profesional on earth sciences from the University of Caldas. My interest lies in micropaleontology of calcareous microfossils, mainly ostracods from Midle Devonian, with approaches to some Cenozoic and cretaceous groups, most recently begin of nannofossils calcareous (marine microalgae). I participated in projects routed on the biostratographic study of some basins of the country of different ages (understood between the last 65 million years). In addition, lead various audiovisual projects aimed at generating timely divulgation and appropriation of the scientific knowledge in the earth sciences. Currently, I belong to the group of Ostracods of this institute.
