Juan Miguel is Head of the Solid-State NMR Platform at CIC energiGUNE (Spain), where he develops and applies ex situ, in situ and operando solid-state NMR methods for energy-storage materials. He earned his PhD in 2006 at the Free University of Berlin, focusing on solid-state NMR approaches to hydrogen transfer and hydrogen bonding. He then carried out postdoctoral research at the Leibniz Institute for Molecular Pharmacology (FMP, Berlin) and the Helmholtz Centre in Munich, applying advanced solid-state and DNP-enhanced NMR to biomolecular solids, including amyloid systems related to Alzheimer’s disease. Since joining CIC energiGUNE in 2012, his work has focused on linking NMR observables to electrochemical function in paramagnetic cathodes, solid electrolytes, carbon electrodes, and metals/alloys, enabling mechanistic insight and materials design.
