Raquel Portes is a physical geographer and PhD in soil science. Raquel’s research projects combine soil science with geology, geomorphology, geochemistry, and geochronology to understand how soils and landscapes coevolve across timescales. She has been using 239+240Pu and d13C as erosion tracers for quantifying and evaluate soil erosion rates. Raquel is arriving from Alaska, after two years leading research projects in the coastal rainforest of Southeast Alaska in collaboration with the Juneau Forestry Science Laboratory, USFS – USDA. Previously, she did her postdoctoral work at the University of Zurich in Switzerland, studying the evolution of soil erosion rates in alpine areas of the Central Rocky Mountains. In her PhD at the Federal University of Viçosa (Brazil) and University of Tübingen (Germany), she examined soil formation and landscape stability across a climate gradient in the Peruvian Andes. At Bates, Raquel is conducting a research on a soil chronosequence on the moraines complex of the Mendenhall Glacier in Juneau, Alaska, and teaching  EACS 307 – Soils and Landscape Evolution this fall and EACS 103 – Earth Surface Environments and Environmental Change in the winter.
