Co-lead for the new Social, Genetic & Environmental Determinants of Health Theme within the NIHR Imperial Biomedical Research Centre (2022 - 2027).

Based at Imperial College (Hammersmith campus), since 1999, I have run in parallel, national clinical services, and research programmes focussing on patients with vasculopathies, particularly pulmonary arteriovenous malformations (PAVMs) and hereditary haemorrhagic telangiectasia (HHT) as the National and for 5 years until Brexit, European  (VASCERN) lead. With a Genetics first degree  (Cambridge, First Class Honours 1984), and PhD (conducted in the Department of Genetics, Harvard Medical School 1993-1996), I have played major roles in the set up and delivery of the West London Genomic Medicine Centre; Imperial’s MSc in Genomic Medicine; the Genomics England Respiratory Clinical Interpretation Partnership (GeCIP) which I have chaired since 2019; and in the NHS North Thames Genomic Service Alliance (GMSA) which I represent on the NHS GMS Research Collaborative Steering Committee. Less well known are that I have set up and delivered major Respiratory Physiology courses, particularly focusing on the pulmonary circulation and oxygen delivery (as Module 1 Lead for Imperial College's iBSc in Remote Medicine) and deliver a programme to train cohorts of students in Data Analysis and Data Presentation enabling better research productivity in their eventual Projects.

Laboratory research foci include identification of new pathogenic genes via the 100,000 Genomes Project, therapeutic reversal of molecular defects that cause HHT, and development of wider bioinformatics and functional tools for medicine in the post genomic era.  Clinical research foci include determining disease-modifying states and quantifiable tools for evaluation.  I continue to focus exclusively on research questions that matter to patients, and the unique foci have provided novel, trans-disciplinary insights into human disease and personalised medicine.
