100%, Basel, fixed-term
The Biophysics Group of Prof. Daniel Müller is part of the strongly interdisciplinary Department Biosystems Science and Engineering. The aim of the department is to explore fundamental properties of biosystems and to use them for the development of tomorrow's biotechnological and medical applications.
Project background
The extracellular matrix (ECM) is a complex three-dimensional network of fibrillar proteins, water, and proteoglycans and is critical for cell fate and function regulation in tissues. Cells sense the biochemical composition and the biophysical properties, such as the architecture and stiffness, of the ECM to regulate a wide variety of cellular functions including adhesion, migration, differentiation, metabolism, mechanics, and growth. In this highly challenging and interdisciplinary project we aim to decipher how cells sense the complexity of the ECM, structurally and biochemically relay the ECM properties into the cell and use this information to establish adhesion. To address this challenge, we will engineer biomimetic fibrillar, multicomponent ECM matrices, apply ultrasensitive atomic force microscopy (AFM)-based single-cell force spectroscopy (SCFS), and engineer cell lines to elucidate the dynamics of cell adhesion initiation and strengthening. To elucidate the molecular pathways regulating adhesion initiation and strengthening, we will use gene editing (CRISPR/Cas), RNAi silencing, and chemical inhibitors. We aim to unravel in molecular detail the decisional processes of how cells establish adhesion to complex ECM compositions and architectures. By MINFLUX nanoscopy, which reaches an optical resolution of ~ 1 nm, we aim to determine how ECM properties determine the molecular architecture of cellular adhesions and their functional implications for signaling. Therewith, we will focus on changes in the molecular adhesion architecture during adhesion maturation, how tension is distributed in the adhesive and on protein dynamics within adhesions.
Job description
This postdoctoral position is embedded in an SNFS-funded research project at the interface of quantitative biophysics, cell biology, materials science, and protein/cell engineering.
Your responsibilities include:
- managing your research and conducting innovative research on integrin-mediated cell adhesion to complex ECMs

Your daily work will include:
- engineering multicomponent fibrillar ECMs
- characterizing these matrices by different methods, including AFM and optical microscopy.
- characterizing how fibroblasts interact with these fibrillar ECMs over different timescales, ranging from seconds to hours
- conducting SCFS experiments
- engineering and validation of cell lines
- sample preparation for MINFLUX nanoscopy
You will have the opportunity to work in a highly innovative and collaborative environment with an outstanding scientific infrastructure, including microscopy, flow cytometry, and genomics facilities. The position is funded for 48 months and is located in the Department of Biosystems Science and Engineering at ETH Zurich in Basel, the planned start date is January 1, 2024. Extension is possible.
