Doctoral Student in -throughput Analysis of Protein-Protein Interactions

The Nash Lab (Lab for Engineering Synthetic Systems) is jointly affiliated with the Department of Chemistry at the University of Basel and the Department of Biosystems Science and Engineering of ETH Zurich (located in Basel). We work at the interface of protein engineering, molecular biophysics, and synthetic biology, developing new experimental and computational approaches to understand and engineer proteins for useful biomedical and industrial applications.

Our research combines high-throughput screening, directed evolution, and single-molecule biophysical methods, and spans projects from fundamental protein science to translational applications.

Many proteins in the human body experience shear stress and other types of mechanical force, and this is believed to play a central role in their activity. Yet we still lack high-throughput techniques to measure how proteins respond to mechanical force. This project will develop high-throughput methods involving molecular surface display and deep sequencing to study force-dependent behavior in protein systems.

These datasets will, in turn, be used to train machine learning models capable of predicting mechanical behaviors of molecular and cellular systems.

As a proof of concept, we will apply this platform to study interactions central to blood clotting, with direct relevance to Von Willebrand disease, a common bleeding disorder. The Doctoral Student will work at the interface of protein engineering, single-molecule biophysics, and machine learning, in close collaboration with a computational biology group (Beerenwinkel) at D-BSSE. The project offers hands-on training across the full pipeline, from high-throughput experimental design to predictive modeling, and the resulting methods and datasets are intended to serve as an open resource for the broader research community.

• Establish and validate a quantitative, high-throughput assay for measuring the mechanical stability of a protein-protein interaction relevant to blood clotting
• Cross-validate high-throughput assay results against AFM measurements
• Design and construct DNA variant libraries and display them on yeast
• Apply next-generation DNA sequencing to quantify phenotypes
• Develop computational pipelines to convert sequencing data into quantitative fitness values
• Collaborate with a computational biology group at D-BSSE to develop and benchmark machine learning models
• Prepare data and manuscripts for publication and present results at lab meetings and conferences
• Enroll in and complete the requirements of the D-BSSE Doctoral program in Basel
• Contribute to undergraduate teaching and practical supervision at the University of Basel

• A Master's degree in bioengineering, chemical engineering, biochemistry, molecular biology, biophysics, or a related field
• A strong quantitative background and genuine interest in protein engineering, mechanobiology, and/or high-throughput experimental methods
• Hands-on experience with molecular biology and protein expression techniques; prior exposure to yeast display, directed evolution, or single-molecule biophysics (e.g., AFM) is an advantage but not required
