The EMAT research group at the Faculty of Science (University of Antwerp) is seeking to fill a postdoctoral researcher position on 5D ED data acquisition, analysis and use of in situ liquid and electrochemical TEM experiments, under the supervision of Professor Joke Hadermann. EMAT is one of the leading electron microscopy centers in the world and has a vast expertise in both fundamental and applied electron microscopy. EMAT has several state of the art electron microscopes including three aberration corrected, high end FEI-Titan instruments, a dual beam FIB, an environmental SEM,... EMAT is also a pioneer in in situ 3D ED studies, as will be important in this project. More about us at our webpage .

Position

This postdoc will be part of a team working overall on the implementation of 5D ED to solve and map the structures within multiphased particles during reactions and during changes in the environment.  Each team member's task is strongly intertwined with the tasks of the other team members.

You will design, train and apply generative models that learn how to complete missing wedges in the reciprocal space of crystal structures. You will work with both synthetic and experimental 3D ED datasets. Your predictions will enable full structure solution and refinement of materials undergoing gas-phase and electrochemical reactions.

You will collaborate with other researchers who apply your tools to MOFs and battery materials.

You will integrate your model into a consistent ML framework together with other development across the team.

The preferred starting date is 1 December 2025. 

Profile

• You hold a PhD in Computer Science, Physics, Engineering or a discipline equally relevant to the topic of the job, or can demonstrate equivalent competences gained through prior work experience.
• You have excellent programming skills.
• You have prior experience developing AI models.
• You are interested in materials science and crystallography and willing to learn the necessary crystallographic skills.
• Experience in solving and refining structures using 3D ED is advantageous.
• You would enjoy working at the interface of instrumentation, analysis, crystallography and materials science.
• Excellent writing and communication skills in English are key assets.
• You are motivated to acquire new skills and work in a multidisciplinary team.
• You act with attention to quality, integrity, creativity and collaboration.
• Your research qualities are in line with the faculty and university research policies .

What we offer

• A full-time appointment as a (postdoctoral) researcher for a period of 12 months, renewable after positive evaluation.
