Our current RMS Diploma students come from a variety of backgrounds and fields. You can find out more about their study projects below

Lightsheet and multiphoton microscopy have been widely used to reduce photo-damage. Here these systems will be used and compared for the imaging of live Drosophila using established cancer model fly lines. A protocol will be established for sample preparation, image acquisition, through to image processing and analysis. Suitability for each technique will be compared for addressing specific questions where live imaging of small model organisms or ex vivo tissues is required. The aim will be to publish these results as a methodology paper with JoVE video protocol.
Distinguishing expensive speciality animal fibres such as cashmere and alpaca from cheaper fibres such as wool is an important activity. Current techniques, such as ISO 17751-2, measure fibre diameter utilising an SEM in 2 dimensions at high vacuum and susceptible to viewing errors. The study will use 3-D imaging techniques to measure and characterise speciality fibres and compare the results with that of current techniques.
With the rise of cryo-EM as a powerful tool for solving protein structures there has been an influx of new researchers learning the technique. Sample optimisation for cryo-EM remains slow and highly inconsistent. This study will aim to create a workflow that will systematically optimise sample preparation much faster for new users. This will be done through a comprehensive assessment of current techniques and then testing these within the context of an EM Facility. A way of simply incorporating tomography into the process will also be developed, as this is a powerful way of assessing ice thickness and protein structure.
Using a multimodal approach to compare precipitate imaging techniques of power generation steels. Both Scanning Electron and Focused Ion Beam (FIB) systems will be used to collect images, employing a combination of modern detectors, and optimised operating parameters for each system. These will be compared to benchmark examples cited in the literature with a view to improving upon the currently referenced standards.
Quantitative single molecule RNA imaging is highly complementary to next generation RNA sequencing approaches. Although lower throughput, imaging has an advantage over sequencing as it reveals subcellular RNA localisation patterns that can have significant consequences for gene regulation. Despite advances in RNA imaging in many other model organisms, for plant biology this approach is currently limited to a few tissues in the model plant Arabidopsis thaliana. The project proposed for this Diploma aims to expand this imaging approach to a wider range of tissues in commercially important crop plants including wheat, sugar beet and oil seed rape.
My study aims to help lift practical scanning electron microscopy into secondary school education, and thus encourage STEM learning by providing teaching staff with teaching materials and lesson notes to match the national curriculum.
Imaging has evolved significantly in the last few years, and no longer involves just the capture of beautiful images, but also the generation of large datasets that must be quantified and analysed. The main goal of this proposal is to develop my image analysis skills, initially through the attendance of courses and subsequently through the development of scripts for ongoing research. These skills will ultimately benefit not only my own research but also the support I provide to users of my imaging facility. I also hope to record my learning experience to help others hoping to develop their own image analysis skills.
Our genome is under constant threat from invasion by mobile genetic elements, including viruses (such as HIV) and retrotransposons (Line 1) which make up 17% of our genome. The Lehner group previously described the Human Silencing Hub (HuSH) complex and showed how it silences genome invaders through chromatin (H3K9me3) modification. HuSH is comprised of three core component proteins: TASOR, MPP8 and Periphilin.
The intracellular localisation of these proteins is poorly characterised, particularly their intranuclear location and role in stem cell differentiation. I intend to utilise Super Resolution and Single Molecule Localisation Microscopy (SMLM) techniques to elucidate the HuSH intranuclear location in human cell lines and at different timepoints during mouse and human stem cell differentiation.
