Juan earned his Bachelor's degree (2000) and PhD in Biology (2005) from the Universidad de Navarra. Since 2010, he has been a researcher in the Hemato-Oncology Program at Cima Universidad de Navarra and is responsible for the Immune Therapies Laboratory. His scientific work focuses on the development of safer and more efficient CAR-T therapies for hematological malignancies,combining cutting-edge genome editing and non-viral technologies. He also investigates the molecular mechanisms governing CAR-T cell function and toxicity, using multiomic approaches at the single-cell level and spatial transcriptomics.
