The Soft Robotics research group from the Department of Mechanical Engineering at KU Leuven focuses on exploring the intersection of soft robotics, mechanical instabilities, and (micro)fabrication. The greater goal is to create intelligent systems that harness the unique characteristics of soft materials and create functionality by means of mechanical design. We focus both on theoretical design, numerical optimization, and experimental validation on prototypes that range from the centimeter to the millimeter scale.
Project
At small scales, fluids behave very differently than we are used to in our daily lives. For instance, fluttering with the feet, like swimmers do, will not propel a millimetre sized person forward. Nature has found an innovative solution to this small scale fluid propulsion problem, in the form of carpets of cilia. These hairlike structures can be found on the surface of cells, where they display a fascinating pattern of deformations: a single cilium changes its movements between forward and backward direction, and a global wavelike motion can be seen across the surface of multiple cilia. These collective dynamics are essential in nature for transporting fluids, particles, and even cells. Despite decades of research, scientists are still uncovering how such rich and highly synchronized motion emerges.
This PhD project aims to mimic the complex movements of cilia arrays using soft robotic technology. While artificial cilia have already been demonstrated in laboratories, they almost always rely on bulky external equipment for actuation and control, which has so far limited their practical use. In this project, we will develop a new generation of compact, self‑contained artificial cilia systems that fit in the palm of your hand and can be operated via only one pressure supply tube.
Profile
Ideal Candidate Requirements
* Master degree in (mechanical) engineering, physics, materials science or equivalent with at least distinction.
* Strong background in solid mechanics, fluid dynamics, and micromanufacturing.
* Familiar with MATLAB/Python, CAD software, FEM analysis, and experimental validation.
* Proficiency in English (written and oral).
* Creative, good problem‑solving skills, ambitious, and a team player.
* Able to work independently, with attention to experimental accuracy and precision.
* Strong communication skills to report results (written and oral).
* Willingness to write a PhD fellowship proposal for national funding.
We are looking for enthusiastic PhD candidates who show a proactive attitude towards research in developing original concepts of actuators.
Offer
* A doctoral scholarship for four years and, if successful, a PhD in Engineering Science.
* A full‑time employment for four years, with an intermediate evaluation after one year.
* Benefits such as health insurance, access to university sports facilities, etc.
* The opportunity to be active in an exciting and international research environment, engage in research collaborations and participate at international conferences.
* An excellent doctoral training at the Arenberg Doctoral School in an international environment at a top European university. This will allow you to gain the skills required to successfully complete your PhD and develop as an independent researcher. Opportunities are provided to acquire deeper knowledge in subjects related to the topic through trainings, summer schools, or lecture series in‑ and outside of KU Leuven.
* Starting date: September 2026 (flexible for the ideal candidate).

KU Leuven wil een inclusieve, respectvolle en sociaal veilige gemeenschap zijn. Wij omarmen diversiteit tussen individuen en groepen als een meerwaarde. Open dialoog en verschillen in perspectief zijn noodzakelijk in een ambitieuze onderzoeks- en onderwijsomgeving. In ons streven naar gelijke kansen erkennen wij de gevolgen van historische ongelijkheden. Wij aanvaarden geen enkele vorm van discriminatie op basis van, onder meer, geslacht, genderidentiteit en -expressie, seksuele oriëntatie, leeftijd, etnische of nationale afkomst, huidskleur, levensbeschouwelijke overtuiging, neurodivergentie, arbeidshandicap, gezondheid, of socio‑economische status.
