About this position
EPFL (École Polytechnique Fédérale de Lausanne) is advertising 1 PhD position in hydrogel acoustic metamaterials within the Laboratory for Bio-Iontronics (BION), led by Prof. Yujia Zhang. The project sits at the intersection of materials science, microengineering, bioengineering, physics, and chemical engineering, with a strong focus on microfluidics, microfabrication, stimulus-responsive hydrogels, ultrasonics, and acoustic metamaterials (acoustic crystals).
The lab’s broader mission is to develop bioiontronic systems for biointerfaces and hybrid intelligent systems, including droplet-based iontronic systems (“dropletronics”) with functions such as embodied energy, logic control, stimulus responsiveness, and therapeutic delivery. The PhD project is described as an emerging, interdisciplinary research challenge focused on developing hydrogel acoustic metamaterials.
Eligibility highlights: applicants should have an MSc in materials science, microengineering, or bioengineering; experience with polymer characterisation and ultrasonics is required; and having more than one peer-reviewed publication is expected. Prior cleanroom manufacturing and 3D printing experience is a plus. The ideal candidate is highly motivated, experimental, independent, creative, solution-oriented, open-minded, and collaborative. English fluency is required; French is a plus.
Funding and contract: the position offers 4 years to complete the PhD with competitive remuneration. The appointment begins as a 1-year fixed-term contract, renewable up to 4 years. EPFL also highlights international collaboration and visiting opportunities.
Application process: applications must be submitted online only. Candidates should upload a single PDF containing a motivation letter, detailed CV, and contact information for at least two references willing to provide recommendation letters. Short-listed candidates will also need to apply to a specific EPFL Doctoral Program to qualify for the PhD (potential programs mentioned: EDMX, EDMI, or EDBB).
Deadline: 25 September 2026. The contract start date is between fall 2026 and spring 2027.
