Matthew Stephens FRS, is the Ralph W Gerard Professor of Statistics and of Human Genetics at the University of Chicago. He received a BA in Mathematics (1992) and Diploma in Mathematical Statistics (1994) from the University of Cambridge UK, and a D.Phil in Statistics (1997) from the University of Oxford UK. Dr Stephens is a statistician and data scientist, who has made seminal contributions to the practice and applications of statistics in genetics. His research interests include analysis of population structure, analysis of genetic association studies (including both complex traits, and molecular phenotypes, such as gene expression and chromatin accessibility), large scale regression and multiple testing. His lab distributes several widely-used software packages for statistical analysis, including PHASE and fastPHASE (for haplotype inference), GEMMA (for association testing) and SuSiE (for variable selection and fine mapping). Dr Stephens's was awarded the Guy Medal in Bronze by the Royal Statistical Society in 2006, was honored as a Medallion Lecturer by the Institute for Mathematical Statistics in 2014, and was included in the Thomson-Reuters list of Highly Cited Researchers 2014.
