With my training in Archeology, I am specialized in Microarcheology, the study of the invisible record, to understand the relationship between humans and plants from a long-term perspective. I obtained my PhD in Archaeology in 1999 after 3 years at the Weizmann Inst of Science working with Prof. S.Weiner. I pioneered in applying quantitative and morphological phytolith analyses to Prehistoric sites aiming to shed new light on the use of fire by past populations. From 2005/13 I founded and directed GEPEG recognized as Quality Research Group by Catalan Government. At pesent, I amb responsible for the Paleoenvironment and Paleovegetation (PALEO) research area within ERAAUB (UB). In 2011 I created PhytCore, the most extensive online phytolith database to date. I have directed more than 20 research projects and written more than 135 contributions (80 SCI). Since 2018 I co-direct the European Advanced research grant TerrACE to study the use of cultivated plants.
