Research Group Leader, Computational and Evolutionary Genomics, EMBL-EBI
John Marioni obtained his PhD in Applied Mathematics in the University of Cambridge in 2008 and did his postdoctoral research in the Department of Human Genetics, University of Chicago. He joined EMBL-EBI as Research Group Leader in Computational and Evolutionary Genomics in 2010. His group develops the computational and statistical tools necessary to exploit high-throughput genomics data, with the aim of understanding the regulation of gene expression and modelling developmental and evolutionary processes. Within this context, the Marioni group focuses on understanding how the divergence of gene expression levels is regulated, using gene expression as a definition of the molecular fingerprint of individual cells to study the evolution of cell types, and modelling spatial variability in gene-expression levels within a tissue or organism. These three strands of research are brought together by single-cell sequencing technologies. John has a joint appointment at the Wellcome Trust Sanger Institute and the Cancer Research UK Cambridge Institute, which is part of the University of Cambridge.
