In 2003 I finished my degree in Earth Sciences at the University of Barcelona, Spain. Immediately, I began to work at the Department of Stratigraphy at the University of Barcelona as a Researcher Assistant. In 2005, I started my PhD at the Institute of Earth Sciences Jaume Almera Ė CSIC (Spain) under the supervision of Santiago Giralt and Roberto Bao which was financed throughout a doctoral fellowship of the Spanish Ministry of Science. At present time I am a Postdoctoral Researcher (funded by the Portuguese Science Foundation) at the Instituto Dom Luiz.

My research focuses on the application of a multiproxy approach, mostly dealing with geochemical and isotopic techniques on different materials, such as water, carbonates, organic matter and biogenic silica to accurately reconstruct the environmental and climatic evolution of a particular region of the Earth. These reconstructions have been carried out using Late Quaternary high-resolution lacustrine sediments, with particular focus on the Pacific and on the North Atlantic regions. The main topic of my climatic research has been to characterize the temporal evolution and the relationship of the ENSO and of the solar activity in the Pacific; and the NAO, EA and SCAND in the Northern Atlantic.
