Dr Graham Horgan

Dr Graham Horgan has 20 years experience of statistical research and consultancy working with scientists involved in nutritional, health, environmental and agricultural research. He has worked for BioSS since 1988 and been Head of the BioSS group at the Rowett Institute since 1997. He has established fruitful collaborative links throughout the Rowett Institute and been involved in the statistical analysis of data collected from a wide range of projects from epidemiological studies at a population level to high dimensional molecular data collected in the laboratory. He has also done contract statistical work for a variety of public and commercial organisations, including the UK Food Standards Agency. This has included collaboration with work on EU funded projects such as NuGO and Diogenes. His work has included statistical methodological development which has led to over 25 first-author papers in the scientific literature, as well as many more where his statistical involvement has led to co-authorship. He has coordinated the BioSS programme of training courses since 1988, and been a presenter on many of these.
