A fully funded PhD position is available at the University of Exeter in the field of optical metamaterials, focusing on the use of micro- and nanoscale 3D printing. The project, supervised by Calum Williams and Maciej Dabrowski, aims to develop 3D-printed optical metamaterials for controlling ultrafast laser pulses on femtosecond timescales. Research will combine nanofabrication (two-photon polymerisation lithography), electromagnetic simulation, and pump–probe laser measurements to explore how 3D geometry and different materials platforms enable advanced light manipulation for next-generation applications in spectroscopy, sensing, and telecommunications. Applicants should have a strong background in physics, optical engineering, or nanotechnology, and a passion for experimental science. The position is fully funded, covering tuition and providing a stipend. The application deadline is October 14, 2025, with a start date in January 2026. Interested candidates should apply via the provided link and may contact Calum Williams for further information.
