Professor Gil McVean tells us how statistical genetics helps us understand and treat disease. Genomic technology and statistical analysis of the genome is a powerful tool in understanding disease. Prof Gil McVean is the Head of Bioinformatics and Statistical Genetics at the Wellcome Trust Centre for Human Genetics. Professor McVean's research covers several areas in the analysis of genetic variation. Combining the development of methods for analysing high throughput sequencing data, theoretical work, and empirical analysis, this research may lead to genetic diagnosis and targeted treatments for disease.
