Job description
The project focuses on the experimental realization and study of artificial microswimmers/microrobots that can move and interact autonomously in 3D environments, mimicking the complex dynamics of microorganisms in fluids.
Living systems such as bacteria or algae exhibit remarkable capabilities: they swim, adapt, interact, and self-organize into dynamic patterns. Understanding and replicating these life-like dynamics in synthetic systems remains a major challenge across physics, chemistry, biophysics, and materials science.
In this PhD project, you will:
§ Develop an experimental platform to study 3D self-organization of active particles.
§ Fabricate and characterize light-driven microswimmers.
§ Use advanced optical microscopy and particle tracking to analyze their motion and interactions.
Investigate emergent behaviors such as swarming, clustering, and collective navigation in confined and complex environments.
The project will build on an interdisciplinary approach, combining concepts and methods from physics, chemistry, and mathematical modelling.
The long-term goal is to derive design principles for constructing smart, adaptive microsystems, potentially useful for targeted drug delivery, cargo transport, biosensing, microfluidic mixing, or self-healing materials.
The successful candidate will join the Active Soft Matter Lab within the TNW Faculty, the MESA+ Institute for Nanotechnology, University of Twente, Enschede, The Netherlands. This position offers ample opportunities for collaboration and interaction with various academic and industrial partners. You will work in a dynamic, highly interdisciplinary environment, utilizing state-of-the-art equipment and facilities to further the understanding and applications of microswimmers.
Starting Date: 1st October 2026 (but negotiable).
Your profile
We are looking for an enthusiastic candidate who meets the following criteria:
A Master’s degree (or equivalent) in (Applied)Physics, Chemistry, Biophysics, or a related field at the interface between Physics and Chemistry. Candidates with an MSc in Chemical Engineering, Materials Engineering, or Mechanical Engineering are also welcome to apply, particularly if their thesis work involved soft matter.
- Experimental Skills (preferred but not mandatory):
Prior experience with experimental techniques, especially in optical microscopy and colloidal particle synthesis, is considered a strong asset.
- Programming and Data Analysis:
Working knowledge or hands-on experience with Python, ImageJ, and/or MATLAB is highly beneficial for image processing and data analysis.
Excellent written and spoken communication skills in English are essential for effective collaboration and dissemination of research findings.
Our offer
- A full-time position for four years, with a qualifier in the first year.
- Your salary and associated conditions are in accordance with the collective labour agreement for Dutch universities (CAO-NU).
- You will receive a gross monthly salary ranging from € 3.059,- (first year) to € 3.881,- (fourth year).
- There are excellent benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, and a solid pension scheme.
- A minimum of 232 leave hours in case of full-time employment based on a formal workweek of 38 hours. A full-time employment in practice means 40 hours a week, therefore resulting in 96 extra leave hours on an annual basis.
- Free access to sports facilities on campus.
- A family-friendly institution that offers parental leave (both paid and unpaid).
- You will have a training programme as part of the Twente Graduate School where you and your supervisors will determine a plan for a suitable education and supervision.

About the department
Our faculty of science and technology (TNW) focuses on three domains, namely Physics, Chemistry, and Health. We are the home base for the research institutes TechMed, MESA+, the Techno Centre for Education and Research TCO, and the Twente Graduate School TGS. TNW offers six Bachelor's and seven Master's programs in (Applied) Physics, Chemistry, Health Sciences, Nanotechnology, and Technical Medicine. Over 850 colleagues and 2,700 students are active within the faculty of Science & Technology. The University of Twente is an equal opportunity employer that values diversity. We do not discriminate on race, religion, color, national origin, gender, sexual orientation, age, marital status, or disability status. Because we value diversity, we particularly encourage women to apply.
Our lab Active Soft Matter is part of the Faculty of Science and Technology and the MESA+ Institute for Nanotechnology at the University of Twente, Enschede, The Netherlands. We focus on active soft matter and bioinspired materials, combining fundamental physics with cutting-edge experimental techniques.
About the organisation
The Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally and is strengthened by the many young researchers working on innovative projects with as doctoral candidates and post-docs. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.
