About me

I am currently a Ramon y Cajal and Ikerbasque Research Associate leading the Laboratory of Humanized Models of Disease.Ā 

Our lab aims at unraveling human astrocyte-specific pathways and mechanisms involved in the pathogenesis and progression of Alzheimer’s disease. Our approaches include the use of humanized in vitro models, chimeric mice and postmortem samples from Alzheimer’s disease patients that allow exploration of human astrocytes at morphological, molecular, biochemical and functional levels.
