I am a geologist who works closely with prehistorians at archaeological sites. In this sense, my scientific career has focused on the study of site formation (both archaeological and palaeontological) through the detailed analysis of fossil remains and sedimentary deposits. For this reason, taphonomy and sedimentology have been the central disciplines developed in my research. I began my research activity on the Miocene sites of Somosaguas and Cerro de los Batallones (Madrid, Spain), resulting in a Master’s Thesis, many JCR publications and, ultimately, my PhD Thesis.Lately, after defending my PhD, my career has been focused on geoarchaeology, unravelling site formation processes and tackling geological issues, working alongside national and international archaeological projects. I have been lucky enough to carry out research on Pleistocene sites at Olduvai Gorge and Nasera Rockshelter (Tanzania; over ten months of fieldwork), at the Calvero de la Higuera sites (Madrid, Spain; six months of fieldwork) and most recently, in El Castillo Cave (Santander, Spain; three excavation campaigns). As for the future, I believe my post-doctoral phase should be not only a period of consolidation of previous knowledge but also one to expand my training and learn other methodologies in order to incorporate them into archaeological sites in which I collaborate. These new lines of study include the use of micromorphological and microstratigraphical analyses of the sedimentary deposits hosting archaeological assemblages. These new methods will certainly provide useful tools to unravel complex site formation processes and better understand the geological history of archaeological sites.
