Outstanding science, strong industrial engagement, and tangible impact are all hallmarks of our PhD programme and of our research culture. Our students work and learn both in UCL's world-class laboratories but also in partnership with a wide range of collaborating institutions and companies worldwide, enhancing knowledge, networking and employment opportunities. Doctoral study at UCL's Department of Mechanical Engineering offers the opportunity to become a world-class interdisciplinary researcher at the interface of science and engineering. Our PhD researchers specialise in applying advanced principles of engineering science to generate new knowledge and introduce innovative solutions to a diverse range of challenges. From biomedical systems to the marine environment, from clean and low carbon power systems to pioneering materials and manufacturing, and in many other fields, we propose ground-breaking technologies that change the world.
