The bioMatter Microfluidics Group led by Dr Eleonora Secchi at ETH Zürich is recruiting two PhD candidates for a fully funded, four-year project focused on the biophysics and rheology of bacterial biofilms. The research aims to uncover the physicochemical mechanisms controlling microbial surface colonisation, biofilm assembly, structure, and mechanical properties, with a special emphasis on the role of extracellular DNA (eDNA) in stress-hardening and adaptation. The project is part of a recently funded SNSF initiative and involves experimental investigation using custom microfluidic and rheometry platforms, advanced imaging, and mathematical modeling. Candidates will work in a highly interdisciplinary, international team within the chair of Prof.

Roman Stocker at the Institute of Environmental Engineering. Applicants should hold a Master’s degree in physics, biophysics, materials science, microbiology, or a related field, and have experience in experimental techniques such as microfluidics, rheology, microscopy, or microbial culturing.

Familiarity with data analysis and quantitative modeling is highly valued. The position offers training opportunities, career development perspectives, and support programmes, with a commitment to diversity and flexible working conditions.

Applications must be submitted online by November 30th, 2025, including CV, cover letter, transcripts, thesis, and two reference letters. For questions, contact Dr Eleonora Secchi at [email protected]. ETH Zürich is a world-leading university in science and technology, offering an inclusive and supportive environment for research and learning.
