This fully funded PhD position at the University of Leuven (KU Leuven) offers an exciting opportunity to contribute to the development of the Einstein Telescope, Europe’s next-generation gravitational wave observatory. The research is embedded within the MPE research group at the Department of Mechanical Engineering, a multidisciplinary team specializing in micromanufacturing, machining of advanced materials, and integration of precision manufacturing systems. The group operates in vibration and environment-controlled labs at the Leuven Nanocenter, equipped with state-of-the-art manufacturing, metrology, and characterization infrastructure.

The project focuses on pioneering non-contact and athermal electrochemical micromachining strategies for the precision machining and polishing of monocrystalline silicon mirror suspension components. These components are critical for the Einstein Telescope and require ultra-high geometric precision, excellent surface and subsurface integrity, damage-free material removal, and controlled 3D shaping capabilities. Research activities will include CNC-controlled Jet-based electrochemical micromachining (Jet-ECM), hybridization with other non-contact or assisted processes, fundamental investigation of electrochemical material removal mechanisms, process modeling and optimization, and surface integrity and subsurface damage characterization.

The PhD candidate will engage in both fundamental and applied research, including hands-on experimental process development, numerical modeling and simulations, mechanical testing, metallography, advanced metrology, and microstructural and surface characterization. Research will be conducted across the Leuven and Geel campuses, leveraging world-class infrastructure. The candidate will collaborate with leading research laboratories in Italy, the Netherlands, and the UK, and will have opportunities to participate in international conferences and scientific dissemination.

Applicants should hold a Master’s degree in Mechanical Engineering, Materials Engineering, Production Engineering, or a related field. Experience with experimental setups, laboratory equipment, design of experiments (DoE), data analysis, and scientific presentation is expected. Basic experience in metallography and metrology techniques is required, while knowledge of electrochemical manufacturing and semiconductor processing is preferred but not mandatory. Strong communication skills, critical thinking, and the ability to work in a multidisciplinary team are essential. Proficiency in English (spoken and written) with TOEFL or IELTS scores is required.

The position offers a fully funded, full-time PhD contract for four years, with annual extensions based on progress. The remuneration package is competitive with industry standards in Belgium, a country known for its high quality of life and excellent healthcare system. The candidate will benefit from excellent guidance by an experienced, international, and multidisciplinary team, access to advanced lab infrastructure, and further doctoral training through the KU Leuven Arenberg Doctoral School. The university is committed to diversity, inclusion, and equal opportunity, providing a supportive environment for all researchers.

To apply, candidates must use the KU Leuven online application platform and submit a motivation letter, academic CV, list of publications, copies of diplomas and supplements, transcript of records, English summary of master thesis, proof of English language proficiency, and a reference letter or contact details. Applications by email are not considered. For further information, contact Prof. Dr. ir. Krishna Kumar Saxena or Dr. ir. Muhammad Hazak Arshad.
