SAGREDO, ESTEBAN

SAGREDO ESTEBANDoctor en Geología de la Universidad de Cincinnati, Estados Unidos y Geógrafo de la Pontificia Universidad Católica de Chile. Sus intereses incluyen paleoclimatología, geomorfología glacial, geocronología cuaternaria, modelación climática/glacial.

Actualmente su trabajo se focaliza en la reconstrucción de la historia paleoclimática del sur de Sudamérica, a través del estudio de avances y retrocesos glaciales ocurridos desde el Último Máximo Glacial hasta el presente.

ENGLISH

I hold a Ph.D. in Geology from the University of Cincinnati, United States, an undergraduate degree in Geography from the Pontificia Universidad Católica de Chile. My interests include paleoclimatology, glacial geomorphology, Quaternary geochronology, and climate/glacial modelling.

Currently, my research focuses on the paleoclimatic reconstructions of southern South America, through the study of glacial fluctuations since the Last Glacial Maximum to the present.
