About the Project
How do we design the next generation of sustainable biomanufacturing processes? Why do microbial strains that perform brilliantly in the laboratory often fail when scaled to industrial production?
This PhD project sits at the intersection of biotechnology, chemical engineering, data science and microfluidics. You will develop an innovative experimental and computational platform to understand how microbial cells behave in the complex environments.
Cell factories are increasingly used to manufacture fuels, speciality chemicals, materials and pharmaceuticals that can replace unsustainable petrochemical processes. However, the major challenge that prevents many promising technologies from reaching commercial deployment is Scale Up. Cells that are engineered and optimised under highly controlled laboratory conditions show dramatic drops in productivity when transferred to industrial bioreactors. Large-scale fermenters expose cells to continuously changing conditions, including fluctuations in oxygen availability, nutrient concentrations, pH and mechanical stress, leading to cellular stress, reduced performance and costly process failures.
To address this challenge, you will develop a novel micro-scale bioreactor platform capable of recreating the environmental heterogeneity experienced in industrial fermentations. Using microfabrication and microfluidics, you will design systems that generate controlled chemical and physical gradients while enabling continuous observation of microbial populations at single-cell resolution. Advanced fluorescence microscopy will be used to measure growth, physiological stress and cellular resource allocation in real time. Alongside the experimental work, you will build predictive computational models that connect environmental conditions with microbial physiology and production performance. These models will combine mechanistic descriptions of cellular processes with modern machine-learning approaches, allowing predictions to be made across environments that have never been experimentally tested. The resulting framework will provide new insights into how microbes respond to industrial-scale heterogeneity and identify design principles for more robust strains and processes.
Using your platform we will redesign and evaluate currently challenging microbial production systems using an iterative design-build-test-learn approach. The most promising new strains and process strategies will be evaluated in bioreactor systems for a validation at laboratory scale.
This project is expected to start in September 2027.
