The world faces enormous challenges that cross borders and disciplinary boundaries. Engineering solutions can help, but not in isolation. The Royal Academy of Engineering’s Frontiers symposia help people to connect and tackle global challenges together. This symposium will bring together outstanding early-mid career researchers, innovators, and practitioners from a wide range of disciplines to collaborate on engineering solutions to global challenges. The event will be hybrid, with participants networking and engaging with each other, and carefully curtated content, via an online platform in their own time, before coming together for two days of intensive networking workshops, both in-person and virtually, on 3 and 4 March.
