Geiger, Alessa J.


alessaGSu experiencia es en la utilización de métodos geomorfológicos, sedimentológicos y geocronológicos para entender los procesos y dinámicas del sistema glaciar durante el Cuaternario. Su trabajo está enfocado en desarrollar un profundo conocimiento sobre la palaeo-glaciología de Patagonia y el cambio climático natural del Hemisferio Sur. La Dra. Geiger es especialista en el análisis de isotopos cosmogénicos, y actualmente está desarrollando mejoras en el procedimiento analítico de 10Be y 26Al en la Pontificia Universidad Católica de Chile.
