Archaeologist, I defended my PhD at the U. of Barcelona in 1999 after 3 years at the Weizmann Inst of Science. I pioneered in applying quantitative and morphological phytolith analyses to Prehistoric hearths to identify fuel uses and collecting strategies. As a result I received in 2005 the Blecua Award (UB). During all these years I have focused on reconstructing the vegetation at different hominid sites such as Olduvai Gorge (Tanzania), being one of the first to use a combined study of modern soils and plants to identify past vegetation. In 2011 I created PhytCore, presently the most extensive phytolith database, covering different geographical and chronological frameworks. I have directed more than 20 research projects and written more than 90 papers and 75 technical reports. In 2005 I founded the Research Group for Paleoecological and Geoarchaeological Studies (GEPEG) recognized as Quality Research Group by Catalan Government which I directed until December 2013.
