Summary
👤
Senior🎓
Top SchoolJulien Barrier is a condensed matter physicist with a decade of experience probing low-dimensional electronic systems and moiré quantum transport, now incoming Research Group Leader at the Max Planck Institute for Solid State Research and concurrently a Research Fellow at ICFO. His work blends experiment and theory—ranging from graphene Josephson junctions to proximity superconductivity in the quantum Hall regime—with publications in Nature and funded independent fellowships such as the EPSRC Doctoral Prize. Julien has a track record of building multidisciplinary projects across top institutions (Manchester, SLAC, CEA) and skills spanning cryogenic transport, nanofabrication, synchrotron techniques and device physics. He also brings lab leadership and teaching experience, having supervised undergraduate labs and led outreach and growth in student organizations. Notably, his background includes materials-focused internships and a patent-pending adhesive technology, reflecting an unusual combination of fundamental physics and applied materials engineering. Based in Barcelona and active in European research networks, he is positioned to translate cutting-edge quantum materials research into new experimental platforms.
