Oier Pastor-Alonso got a PhD in Neuroscience from the University of the Basque Country in 2020. Using mouse models, he studied the developmental formation and establishment of adult hippocampal neural stem cells and the mechanisms guiding their response in the context of medial temporal lobe epilepsy. He joined the lab in 2021 to explore the prenatal and postnatal development of neural stem and progenitor cells in the human hippocampus. His current interests move towards the study of the human infant and adult hippocampus and plasticity changes after seizures.
