I obtained a PhD in Archaeology from 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 sites to identify fuel for human fires and plant collecting strategies. In 2005 I received the Blecua Award (UB). My research focuses on reconstructing the vegetation from different sites such as Olduvai Gorge (Tanzania), applying a combined study of modern soils and plants. In 2011 I created PhytCore, the most extensive phytolith database to date. I have directed more than 20 research projects and written more than 100 papers. From 2005-2013 I founded and directed GEPEG recognized as Quality Research Group by Catalan Government. At present, I am responsible for the "Paleoenvironmental and paleovegetation" research area within ERAAUB and I participate, among others, in a European funded Project "Terrace" to study the use cultivated plants.
