President of Ireland Young Researchers Award 2012
I run a translational medicine research programme focused on investigation of pathogenesis and discovery of biomarkers of disease in glomerulonephritis. My principal research interest is in ANCA vasculitis, an autoimmune condition that causes multi-organ failure as a consequence of overwhelming necrotising inflammation affecting small blood vessels. My lab spans cellular immunology in the Trinity Translational Medicine Institute and health data informatics in the ADAPT SFI Centre. We are addressing the following questions: 1. What biomarkers accurately track glomerular inflammation in ANCA vasculitis? 2. What molecular and cellular events lead to myeloid cell dysfunction in ANCA vasculitis? 3. What underpins the large variability in clinical phenotype observed in ANCA associated vasculitis? 4. How can we minimise the adverse events associated with existing immunosuppressive therapies? 5. How do we predict relapse in ANCA vasculitis? This research spans two primary areas: 1. Health data informatics. Massive challenges exist in this area in Ireland, where health data is fragmented and difficult to access. I currently lead a trans-disciplinary "Chronic Disease Informatics Group", which links basic immunology, health informatics and data analytics. The HELICAL (HEalth data LInkage for ClinicAL benefit) MSCA Innovative Training Network explored the impact of health and research data linkage to address complex challenges in autoimmune disease. It was followed by the FAIRVASC (Building registry interoperability to inform clinical care) European Joint Programme for Rare Diseases funded EU consortium, which used a knowledge graph approach to link rare disease registries for the first time into a federated learning platform. We applied semantic web technology to large scale data integration challenges in autoimmune disease, leading to a pipeline for multi-modal algorithm development and linkage to, for example, environmental datasets. This semantic web user interface now runs queries over federated databases containing >5000 patients across Europe and will become part of the rare disease discovery platform under development by the European Joint Programme for Rare Disease. An example of application of this data linkage approach is the discovery that ultraviolet-B radiation exposure is linked to autoimmune disease relapse. 2. Translational immunology of autoimmune disease, specifically the rare immune disorder ANCA vasculitis. A cornerstone of this was creation of a national biobank and registry of patients with this disease (RITA-Ireland registry and biobank), which is now among the most extensive globally. This has provided an unrivalled substrate for biomarker discovery, the most impactful of which is urine sCD163. This translational work extends into study of disease pathogenesis using primary biological samples and data, for example the identification of novel subsets of neutrophils and monocytes in ANCA vasculitis. Linking this with the heath data informatics research, the PARADISE (PersonAlisation of RelApse risk in autoimmune DISEase) ERA-PerMed funded EU consortium is currently driving translational innovation, applying multi-modal deep phenotyping to develop algorithms for individual level prediction of vasculitis relapse. Aligning with the FAIRVASC initiative, I lead a trans-European data linkage infrastructure for ANCA vasculitis, which integrates clinical (from registries), biomarker (proteomic, transcriptomic and genomic) and patient-reported data (from wearable devices) at the level of the individual, supporting multi-modal assessment and personalised medicine.
