Paul O'Reilly

I am a Senior Lecturer in Statistical Genetics at the MRC SGDP Centre, Institute of Psychiatry, King's College London. I did my PhD at Imperial College London on detecting recent positive selection in the human genome, supervised by David Balding and co-supervised by Ewan Birney. After a post-doc with Marjo-Riitta Jarvelin and Lachlan Coin, working on numerous GWAS projects and methodology development focused on multivariate GWAS (MultiPhen) and inversion polymorphisms, I began a lectureship in the same dept. in 2011, before moving to King's in October 2013. I'm interested in working on quantitative problems in population genetics and genetic epidemiology.

Previously, at Imperial College London, I taught statistics & epidemiology on the Medicine Undergraduate course, and statistics and statistical genetics on the MSc Bioinformatics, MSc Modern Epidemiology and Masters in Public Health courses.

Other roles

I am the Deputy Programme Leader of the MSc Genes Environment and Development and a scientific director (along with Cathryn Lewis) of the Summer School: Analysis of Genetic Association Studies at the MRC SGDP Centre, IoPPN, King's College London. I am an Associate Editor for BMC Genomics.
