He is currently working on a doctoral thesis on the population dynamics of the Solutrean hunter-gatherer groups in inland iberia from the perspective of the analysis of lithic assemblages. Since 2024 he has been a technician in the Experimental Archaeology Laboratory at the CENIEH, where he carries out tasks related to the resolution of archaeological problems through experimentation with mainly lithic and bone materials, as well as the analysis of Pleistocene and Holocene lithic collections.
