Ph.D. in Prehistory (University of Salamanca, Spain) and Master Degree in Primatology (University of Barcelona, Spain). She was trained in several national and international centres (CSIC, CNRS IPGQ Bordeaux) and was a visiting researcher at the Leverhulme Center for Human Evolutionary Studies (LCHES), University of Cambridge (UK), and at Seattle Pacific University (Washington, USA). Since 2005 she is a researcher in Palaeophysiology and Human Ecology at the National Research Centre on Human Evolution (CENIEH, Burgos, Spain). Dr Mateos participated in the Atapuerca Research Team for 21 years. Since 1997 she has also conducted excavation projects in Uruguay, Bulgaria and Spain. Her research lines are focused on the biological and ecological study of modern humans, extinct species and other primates, under the framework of Human Behavioural Ecology, Trophic Ecology and Human Ecophysiology. Dr Mateos collaborates in the study of Human Palaeoecology in Pleistocene Europe with the Palaeoecology of Mammals group at CENIEH for more than a decade. This research highlights the role of humans in the natural food webs. She was co-leader of the international scientific network METHOD (IFG 1604F, INQUA-HabCom) from 2014 to 2019, and she is currently a member of the TROPHIc Project (PID2019-105101GB-I00), along with Dr Jesús Rodríguez (CENIEH) and other researchers from Trier Lab for Social Simulation (TRILABS) at Trier University, and German Research Centre for Artificial Intelligence (DFKI). She uses mathematical modelling and computer simulation in her research lines. Additionally, she develops programs of experimental energetics, cineanthropometry, biomechanics, and motion analysis in the re-enactment of Pleistocene activities.
