Specialist on microfossils

Most of us have gone to places where the landscape just takes our breath away. Places where the beauty of the ocean, mountains or valleys are just inspiring!!!... So, we just have to wonder how such landscapes were formed and preserved! Well, having that feeling and wondering such things is what I got to do thanks to my professional career.. 

Yes, I am Geologist, and within this vast field, I have specialized on study small-sized fossils (microfossils). They can be either from continental (pollen and spores) or marine (foraminifers) settings. I use them for understanding the evolution of some living forms and ecosystems throughout time, for reconstructing features of ancients environments, but also for building up relative time frames (bio/chronostratigraphy). 

 

What I do, although it may seem a bit romantic or even useless, has several applications in different fields, and I would say that one of the main uses is providing extremely valuable information to the oil industry. Having accurate and reliable data on the age, type, and environments of the rocks can save millions of dollars!

​

In this project, I will focus on generate robust time frames for the Pisco Basin, which will allow understanding when key (geological or biological) processes took place.
