A fully-funded PhD position is available at the University of Exeter in the field of optical metamaterials, focusing on the ultrafast control of laser pulses using 3D-printed micro- and nanoscale structures. The project, supervised by Calum Williams and Maciej Dabrowski, will involve developing advanced metamaterials to manipulate light on femtosecond timescales. Research activities include nanofabrication using two-photon polymerisation lithography, electromagnetic simulation, and pump–probe laser measurements. The aim is to explore how 3D geometry and different material platforms can enable new capabilities in light manipulation for applications in spectroscopy, sensing, and telecommunications. The position is open to UK students only and seeks candidates with a strong background in physics, optical engineering, or nanotechnology, and a passion for experimental science. Funding is fully provided, covering tuition and a stipend. The application deadline is 14th October 2025, with a start date in January 2026. Interested applicants should apply via the University of Exeter portal and may contact Calum Williams for informal enquiries.
