Ultra-sensitive 3D molecular assays using total body PET and deep learning. Recent advances in biomedical engineering have led to the development of Total Body Positron Emission Tomography (TB-PET), the most sensitive imaging device to date. Despite these impressive engineering advances, computational methods lag far behind and model-based approaches cannot deal with the complexity or volume of data these systems produce. We will develop new computational methods based on deep learning and stati ....Ultra-sensitive 3D molecular assays using total body PET and deep learning. Recent advances in biomedical engineering have led to the development of Total Body Positron Emission Tomography (TB-PET), the most sensitive imaging device to date. Despite these impressive engineering advances, computational methods lag far behind and model-based approaches cannot deal with the complexity or volume of data these systems produce. We will develop new computational methods based on deep learning and statistical methods that fully exploit the richness and complexity of the data generated by TB-PET, enabling 3D quantitative assays of molecular processes throughout the entire human body with unparalleled sensitivity. The technology we create will open up new capability for the study of complex physiological systems.Read moreRead less
Novel tractography-guided MRI methods for studying healthy brain ageing. Advances in imaging, and particularly Magnetic Resonance Imaging, have opened a new era in the study of the brain enabling a myriad of neuroscience discoveries. This project aims to develop new analysis methods to study and understand the variability in the human brain during ageing, exploiting the wealth of information contained in the so-called tractogram, a mapping of the brain’s wiring.

Advances in imaging, and particularly Magnetic Resonance Imaging, have opened a new era in the study of the brain enabling a myriad of neuroscience discoveries. This project aims to develop new analysis methods to study and understand the variability in the human brain during ageing, exploiting the wealth of information contained in the so-called tractogram, a mapping of the brain’s wiring. This project expects to develop innovative imaging biomarkers to characterise the brain changes in the course of healthy brain ageing. Expected outcomes include novel imaging tools for neuroscience, which should allow us to map trajectories of normative healthy brain ageing and use them to identify lifestyle factors that impact these trajectories.Read moreRead less
Creating a non-invasive window into the mind. This project aims to create better tools to study the human mind. This project expects to generate new knowledge that can be used to non-invasively image neuronal activity.

This project aims to create better tools to study the human mind. This project expects to generate new knowledge that can be used to non-invasively image neuronal activity. Expected outcomes include the development of unique new Magnetic Resonance Imaging (MRI) instruments to study neuronal activity in both highly controlled laboratory conditions and in humans, with the spatial and temporal resolution needed to study the neuronal circuitry that drives low and high-level brain functions, i.e., creating a window into the mind. In the future, outcomes from this study could improve our understanding of mental disorders, advance computer brain interface technology, and inspire the next paradigm shift in artificial intelligence.Read moreRead less

Self-Supervised Sequential Biomedical Image-Omics. This project aims to develop a self-supervised sequential biomedical image-omics model to uncover the underlying biological processes e.g., normal or abnormal. Sequential biomedical images are state-of-the-art imaging modalities which allow to depict changes in progression to the human body. New self-supervised machine learning algorithms are proposed to derive features from heterogenous and unlabelled sequential images. These derived features w ....Self-Supervised Sequential Biomedical Image-Omics. This project aims to develop a self-supervised sequential biomedical image-omics model to uncover the underlying biological processes e.g., normal or abnormal. Sequential biomedical images are state-of-the-art imaging modalities which allow to depict changes in progression to the human body. New self-supervised machine learning algorithms are proposed to derive features from heterogenous and unlabelled sequential images. These derived features will then be used to characterise the morphological and functional changes, which provide opportunities to increase understanding of progression of diseases of individual subject. The outcome from this project will provide new insights into system biology with potential future benefits in healthcare.Read moreRead less
Motion-adaptive PET technology for brain imaging of freely moving mice. This project aims to develop new brain imaging technology that adapts to and corrects for the motion of a responsive, freely moving mouse. Current technology requires the subject to be unconscious, precluding the use of imaging to study signalling pathways activated by external stimuli during cognitive and behavioural tasks. By harnessing new radiation detector, motion tracking and computational technologies, the project exp ....Motion-adaptive PET technology for brain imaging of freely moving mice. This project aims to develop new brain imaging technology that adapts to and corrects for the motion of a responsive, freely moving mouse. Current technology requires the subject to be unconscious, precluding the use of imaging to study signalling pathways activated by external stimuli during cognitive and behavioural tasks. By harnessing new radiation detector, motion tracking and computational technologies, the project expects to bridge this technology gap and provide significant technical and conceptual advances in the field. This will provide important benefits, such as equipping neuroscientists with new tools to answer fundamental questions about how the mammalian brain regulates behavioural adaptation to a changing environment.Read moreRead less

This project aims to develop 1- novel protocols to generate clinically-relevant wear particles from spinal implants in-vitro and 2- a technological framework for the fabrication of a novel microfluidic 3D spinal implant-on-a-chip with tailored mechanical, material and biological properties. This will provide a cost-effective tool, currently unavailable, that allows investigation into the impact of wear particles on healthy spinal disc cells. We expect our technological framework to become an invaluable tool for biomedical engineers, biologists, and bio-engineers to work together and generate clinically relevant in-vitro data that supports optimisation for spinal implant design, fabrication, and safety.

A Multi-Optrode Array for Closed-Loop Bionics. We will design, implement and characterise a disruptive multi-channel optrode array (MOA) to record and stimulate excitable living tissue. The MOA will be a combination of individual optical electrodes (optrodes) that either comprise a new class of liquid crystals, used to passively sense extracellular biopotentials, or microphotovoltaic cells that will be used for electrical stimulation of excitable tissue.

By employing light for communication with optrodes, this new approach alleviates many of the wiring, packaging and encapsulation issues associated with existing devices. Computational modelling and in vitro testing in cardiac tissue and retinal neurons will demonstrate the utility of the MOA to sense and control electrical activity.Read moreRead less
