Oscar Ercilla is a predoctoral researcher at the Center for Astrobiology (CAB). His research is based on the dielectrical properties of icy moons analogs for radar exploration. Previously he has worked in laboratory and research tasks in Spain on construction materials and in Chile doing metallogenic mapping and the study of salt flats in the Andes Highlands. His professional work has allowed him to have an advanced knowledge of laboratory and field work, having carried out and organized campaigns at high geographical altitude in similar conditions of isolation to those that will be encountered on the ship. His work at the CAB has allowed him to gain advanced knowledge in Raman spectroscopy which is intended to be used in the expedition.

Oscar has a degree in geology from the University of Salamanca (Spain) and the University of Chile.
