A fully funded 39 month position is available at the University of Sheffield in the field of Surface engineering & tribology for silicone-free consumer products, funded by EPSRC.
The project aims to decode the fundamental polymer physics/chemistry of lubrication and slip planes across complex, heterogeneous surfaces, using explainable machine learning and materials informatics to rationally design sustainable, high-performance formulations.
You will be responsible for developing explainable machine learning models (symbolic regression, Bayesian optimisation, and genetic algorithms) to decode polymer-solvent thermodynamics and map soft-matter physics to real world applications. The position involves featurizing complex polymer architectures, analysing multi-modal experimental datasets, and creating open-source cheminformatics tools in Python/Julia for sustainable inverse formulation design and AI-driven materials discovery. The work is a highly collaborative project between Dr Grant Hill and colleagues within the School of Mathematical and Physical Sciences, and an industrial partner. The project requires a high degree of independence, strong computational skills, and the initiative to bridge theoretical polymer chemistry with experimental data.
Main duties and responsibilities
- Algorithm development: Develop and benchmark explainable machine learning models to predict how polymers interact with solvents.
- Data integration & featurization: Process and featurize complex polymer architectures to link molecular structure with bulk properties.
- Open-source software delivery: Build, document and maintain well-structured, open-source computational tools and workflows in Python/Julia, releasing them via GitHub.
- Interdisciplinary collaboration: Work closely with the whole project team to validate model predictions against real-world data.
- Dissemination: Prepare high-quality manuscripts for peer-reviewed publication and present research findings at national and international conferences.
- Carry out other duties, commensurate with the grade and remit of the post.
