My research uses rigorous spatial quantitative methods to study a range of epidemiological questions related to non-communicable disease, global health and low- and middle-income countries.
Current projects include a comparison of space-time methods for non-communicable disease surveillance funded by the Wellcome Trust; the development of the Rapid Inquiry Facility - a software for disease mapping and risk analysis; modelling of spatial uncertainty with Emory and Harvard researchers, funded by NIH; and collaborative projects with Brazil, India, Nigeria and the Democratic Republic of the Congo.
I am a leading expert of the epidemiology and health burden of sickle-cell disease and other haemoglobinopathies. I assembled contemporary evidence to inform public health policies in order to better prevent and manage these disorders, and ultimately improving the quality of life of patients. I am an expert of haemoglobinopathies for the Global Burden of Disease (GBD) Study.
I am the Imperial lead for the Theme 1 - Epidemiological assessment of low level environmental exposures of the National Institute for Health Research (NIHR) Health Protection Research Unit (HPRU) in Health Impact of Environmental Hazards. I work in collaboration with Public Health England and the National Environmental Public Health Tracking of the US Centers for Disease Control and Prevention (CDC).
I am also the Training Programme Coordinator for the MRC-PHE Centre for Environment and Health, which is a joint collaboration betwen Imperial College London and Kings College London, to offer the best training and career development opportunities to PhD students and early-career fellows.
I acted as the Assitant Director of the UK Small Area Health Statistics Unit (SAHSU) between May and October 2018.
I am supervising PhD studentships on environmental factors and the severity of cystic fibrosis, with funding from the Cystic Fibrosis Trust and Imperial's MRC-DTP. I am a mentor within the School of Public Health.
My work was published in prestigious medical journals including The New England Journal of Medicine, The Lancet, The Lancet Global Health and PLOS Medicine.
I am a member of the Editorial Board for the Transactions of the Royal Society of Tropical Medicine & Hygiene and for the Journal of Zhejiang University-SCIENCE B (Biomedicine & Biotechnology).
