Project Description

Super-resolution microscopes, celebrated in the 2014 Nobel Prize for Chemistry, are one of the tools that allow us to study immune cells in unprecedented detail. Recently, my research team has used these microscopes to study the changing arrangements of molecules on the surface of immune cells as they survey other cells for signs of disease. My lab now aims to compare how the surface organisation of Natural Killer cells and macrophages, varies in health and disease, as well as in individuals with variations in immune system genes. We will test how the structure of cell surfaces impacts the thresholds at which immune responses are turned on and off. As well as understanding how immune cells work, we hope to uncover new ways in which medicines can nudge their activity up or down.

A PhD project is available to explore how the nanoscale organisation of cell surface proteins impacts signaling thresholds in human Natural Killer cells. A particular unknown is what mechanisms are important is how receptors are organised at the cell surface. Here, we will study how the cytoskeleton, lipid rafts, and tetraspanin scaffold proteins impact the clustering of cell surface receptors, and in turn how this impacts downstream signaling and overall immune responses. This project is highly multi-disciplinary – involving state-of-the-art and novel microscopy, quantitative image analysis as well as molecular and cell biology. This project will run in conjunction with a £1.8m WT Investigator Award to our lab to broadly investigate how the nanoscale organisation of immune cell surfaces impacts health and disease.

The project is highly multi-disciplinary – involving state-of-the-art and novel microscopy, quantitative image analysis and cell biology, and the use of clinical samples. Davis’s lab has published over 100 papers in imaging immune cell biology. Many PhD students from Davis’s lab have gone on to high-level positions afterwards, in academia or in industry, including posts in Harvard University, Oxford, Cambridge and several now hold major permanent faculty positions.


Entry Requirements:

Outstanding scores in an undergraduate or a Master’s degree are required. Some experience in human immune cell biology or microscopy is required.

For international students we also offer a unique 4 year PhD programme that gives you the opportunity to undertake an accredited Teaching Certificate whilst carrying out an independent research project across a range of biological, medical and health sciences.
