Hilary is IOM's Research Director. She is a Fellow of the Royal Statistical Society. Hilary has extensive experience in the design and analysis of epidemiological morbidity and mortality studies. She has been project leader of a number of studies including a detailed statistical analysis of the relationship between exposure to inspirable dust and the presence of respiratory symptoms among UK wool textile workers, and a study of the inter-relationships of dust exposure, lung function and respiratory symptoms among workers in a variety of industries (including underground coal miners and opencast workers). Much of her work has been concerned with the investigation of exposure-response relationships, primarily among occupational populations.
