This PhD position at the University of Twente is part of the Membrane Surface Science (MSuS) group within the Department of Membrane Science & Technology (MST) and the Molecular Nanofabrication group in the Department of Molecules and Materials. The project centers on the development and characterization of new, sustainable membranes, which are crucial for safe drinking water production and waste stream treatment. Traditional membrane fabrication relies on harmful aprotic solvents, but this research aims to pioneer a solvent-free method using the complexation of charged polyelectrolytes, with water as the only solvent. Advanced foaming techniques will be employed to control membrane porosity and pore size, directly linking material properties to membrane performance.

The position is embedded in a larger NWO-VICI project, fostering collaboration with other PhD students and a postdoc focused on related aspects such as advanced functionalities and upscaling. The research environment is highly collaborative, with integration into the MSuS and MnF groups, and offers extensive opportunities for knowledge exchange. The successful candidate will participate in the Twente Graduate School and other graduate education programs, and contribute to teaching by supervising BSc and MSc assignments or assisting in departmental courses.

The Membrane Science and Technology department is internationally recognized, with a strong history in membrane research, over 250 PhD graduates, and significant scientific output. The Faculty of Science & Technology at the University of Twente is a leading institution in chemical technology, applied physics, and biomedical technology, with strong industry and research partnerships. The position offers a four-year contract, competitive salary, excellent benefits, and a supportive, family-friendly work environment.

Applicants should have a relevant Master’s degree, strong motivation, and affinity for physical chemistry, materials science, and water treatment. Experience with polyelectrolytes and related processes is preferred. English proficiency is required, and the selection process may include a written test and scientific presentation.

Applications should be submitted online by 16 November 2025, including a cover letter, CV, transcripts, and references. For further information, contact Prof.

Wiebe M. de Vos.
