2026年9月3日

Are you a motivated PhD candidate who wants to help shape the future of crystallization in the pharmaceutical industry. In this project, you will work at the interface between chemical engineering, process technology, and industrial pharmaceutical manufacturing. The aim is to develop and test continuous crystallization-in-flow concepts that can make production of intermediates more robust and efficient. You will explore how flow-based crystallizers can improve control of crystal quality, purity, particle size distribution to interface with downstream handling by filtration and washing. The project combines literature insights and experimental work, with a particularly strong focus on equipment development in close collaboration with H. Lundbeck. 

The work may include batch experiments, flow experiments, online and offline analysis, proof-of-concept testing, process optimization, and scale-up considerations. You will contribute to solving real challenges in pharmaceutical production, where small improvements in crystal properties can have major impact on quality, cost, and manufacturability. The project is suited for a candidate who enjoys experimental research, process understanding, hands-on equipment development, and translating scientific insight into practical technology. You will become part of an ambitious research environment at DTU Chemical Engineering and contribute to developing technologies that makes pharmaceutical manufacturing more reliable.

Responsibilities and qualifications
Your main responsibility will be to develop, test, and evaluate continuous crystallization concepts for pharmaceutical intermediates. You will carry out a literature review of continuous crystallization technologies and use this knowledge to identify promising flow configurations and key operating parameters. The work will include planning and conducting flow crystallization experiments and developing new or improved laboratory-scale crystallizer setups. You will investigate how parameters such as mixing, temperature profiles, residence time, flow rates, and crystallizer design affect product quality, purity, filterability, particle size distribution, and downstream handling. You will also contribute to translating laboratory results into industrial implementation. Part of the work will take place at H. Lundbeck’s production site in Lumsås near Nykøbing Sjælland.

• You should have a strong background in chemical engineering, process engineering, or a related field.
• Experience with crystallization, separation processes, reaction engineering, fluid flow, particle technology, or pharmaceutical process development is an advantage.
• You are motivated by experimental research and enjoy hands-on work with laboratory equipment, process setups, troubleshooting, and data analysis.
• You are curious, systematic, and able to combine fundamental process understanding with practical technology development.
• You have good communication skills in English and are motivated to work in an interdisciplinary environment with both academic and industrial partners.

You must have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree[HS2]  in chemical engineering, process engineering, or a related field.
