About

I'm a materials scientist with over four years' experience at the intersection of nanostructuring, magnetic characterisation, and materials processing, focused on developing high-performance permanent magnets without rare-earth elements. My PhD was conducted in close collaboration with industry within a European project consortium, which has shaped my priorities ever since: research that translates into something a company can actually use. More recently, that same mindset has led me to explore 3D-printed architectures for battery applications. Along the way, I've pushed magnetic materials beyond conventional thermal stability and coercivity limits and, more recently, successfully printed complex structures incorporating various active battery materials. I also stepped into a scientific advisory role, bridging our research with industry partners and EU evaluators, and helped organise international conferences on magnetism. That mix of technical depth and stakeholder-facing experience is where I add the most value. What drives me is simple: technology that matters for where energy and materials are headed next, from permanent magnets to more efficient energy storage. If you're working on challenges in that space, I'd love to compare notes over a coffee.

Experience

  • Researcher at Instituto de Micro y Nanotecnología (IMN-CNM,CSIC)
    Dec 2025 - Present · 8 mos

    Working on the synthesis and characterisation of 3D-printed structures for energy storage applications in Li-ion batteries under the supervision of Dr. Ester Palmero. • Developed complex 3D-printed architectures using stereolithography (SLA), engineered to maximise surface-to-volume ratio for improved battery performance. • Formulated and processed structures incorporating a range of active materials, including graphite, copper particles, carbon nanotubes, and metallic nanowires. • Participated building process know-how from the ground up together, including settling trials on resin and active material formulations. • Combined additive manufacturing with materials characterisation to evaluate structural and electrochemical performance of printed electrodes.

  • IMDEA Nanociencia (3 yrs 5 mos)
    • Predoctoral researcher
      Oct 2022 - Sep 2025 · 3 yrs

      "Strontium ferrite nanocomposite permanent magnet material with enhanced thermal stability" Developed the experimental research programme exploring the nanostructuring of strontium hexaferrite below the single-domain size regime, under the supervision of Prof. Alberto Bollero and Dr. Ester Palmero, as part of the European PASSENGER consortium project. • Conceived and carried out the synthesis study, including cryomilling, systematic variations in milling parameters, and controlled atmosphere conditions during recrystallisation, to tailor microstructure and magnetic properties. • Established correlations between morphological, microstructural, and magnetic functional properties across the different processing routes, and developed densified permanent magnets via conventional sintering. • Acted as scientific advisor for the strontium ferrite work in the second half of the project, liaising with industry partners and EU evaluators on progress and results. • Represented the group at EIT Raw Materials Week and the Raw Materials Summit, and delivered an invited talk in Brussels on achieving EU independence with rare-earth-free magnets. • Presented research at numerous international conferences and workshops, including JEMS 2023 (Madrid), ICM 2024 (Bologna), REPM 2025 (Tsukuba), and JEMS 2025 (Frankfurt), through oral and poster communications. • Sat on the organising committee for JEMS 2023 and Young Researchers in Magnetism 2025, handling logistics, speaker coordination, and event planning.

    • Research Assistant
      May 2022 - Oct 2022 · 6 mos

      Six-month foundational research position ahead of starting my PhD, focused on building the technical and scientific groundwork for the Sr-hexaferrite work that would become my thesis. • Trained on the key experimental equipment and techniques used across the group, including electron microscopy, x-ray diffraction, and magnetometry. • Conducted an in-depth literature review on strontium hexaferrite materials to identify open questions and define the initial research direction. • Ran the first exploratory experiments of what would later become my PhD thesis. • Presented early results at a PASSENGER project consortium meeting, my first exposure to reporting research progress to industry partners.
