Sagredo, Esteban
Doctor en Geología de la Universidad de Cincinnati, Estados Unidos; Magíster en Ciencias con Mención en Ecología y Biología Evolutiva de la Universidad de Chile; 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.
I hold a Ph.D. in Geology from the University of Cincinnati, United States, a Master of Science degree (mention in Ecology and Evolutionary Biology) from Universidad de Chile, and 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.
