About us

University College London (UCL) UCL is a multi-disciplinary university with a population of over 13,000 staff and 42,000 students from 150 different countries. Degree programmes are provided in Arts and Humanities, Built Environment, Brain Sciences, Engineering Sciences, Education, Laws, Life Sciences, Mathematical & Physical Sciences, Medical Sciences, Population Health Sciences and Social and Historical Sciences. For more information, please visit UCL Engineering Engineering Sciences comprises ten academic departments that undertake research and teaching across a wide range of disciplines. Our scientists and engineers take discoveries from fundamentals to practice, producing innovative technological solutions to challenging problems. It is a dynamic and growing faculty, with a strong vision and desire to use our talents to ‘Change the world’. For more information see The University College London activity at Harwell The postholder will work in the Materials, Structures & Manufacturing Group at Harwell Campus ([email protected]) led Dr. Leung and Prof. Lee. The group is based in the Research Complex at Harwell (RCaH,, Rutherford Appleton Laboratory (RAL), in Oxfordshire. The group’s research projects are strongly linked to the large facilities, including the European Synchrotron Radiation Facility (ESRF), Advanced Photon Source (APS), together with Diamond Light Source (DLS), ISIS Neutron Source and the Central Laser Facilities at Harwell Campus. The Department of Mechanical Engineering at UCL is an internationally recognised centre of excellence for the fields of advanced materials, materials processing, and modelling. The Mechanical Engineering Department at UCL began in 1847 with the appointment of a “Professor of Mechanical Principles of Engineering”, the first mechanical engineering chair in the country. This appointment is subject to UCL Terms and Conditions of Service for Research Professional Services Staff. Please visit for more information. Please note this post is funded for three years in the first instance.

About the role

The project is funded by UCL on a grant from the EPSRC. The assignment provides a unique opportunity to interact with world-class academics, industrial researchers, and access to exceptional processing and microstructural characterisation facilities. Laser powder bed fusion (LPBF) is a disruptive digital technology that employs a focused laser beam to build a component with intricate features, directly from a digital file. The high-energy laser beam can cause vaporisation of alloy elements during printing, resulting in compositional changes and the formation of imperfections, deteriorating both structural integrity and product safety of the LPBF component. In this project, you will develop a chemical imaging instrument for additive manufacturing (AM) machines that is capable of imaging and analysing the plume composition, enabling users to dynamically control and minimise the plume and defect generation during LPBF. You will verify your finding using correlative X-ray and chemical imaging coupled with machine-learning models. Your work will provide crucial to inform, validate and progress an open-source high-fidelity AM simulation that predicts multiphase interactions and formation of imperfections during LPBF. You will have the opportunity to work with original equipment manufacturing for AM machine as well as world-leading scientists in instrument design, X-ray and chemical imaging, machine-learning, and process simulation.

About you

The post-holder will have a PhD qualification awarded for research and extensive knowledge and expertise in laser optics, signal processing, spectroscopy, machine learning, or related field. Ideally, you would also have experience in imaging and image analysis. Your expertise should be at a level appropriate for the conduct of research and publishing new knowledge in leading international research journals. The post-holder will need to show a high level of initiative and the ability to work collaboratively and independently. Applicants should have good team-working skills and a strong command of English. Ideally, you would have a proven track record in spectroscopy, signal, and image processing. Please see the job description and person specification for more information.
