Dr John Marioni

Associate Faculty

John Marioni's group develop computational and statistical tools to exploit high-throughput genomics data to understand the regulation of gene expression and to model developmental and evolutionary processes. His team has pioneered approaches for analysing single-cell transcriptomics data and, together with four colleagues, he co-ordinates the Sanger Institute-EBI Single-Cell Genomics Centre.

John graduated from the University of Edinburgh in 2003 with a BSc in Mathematics and Statistics before obtaining an MPhil in Statistical Science at the University of Cambridge in 2004. Subsequently, he read for a PhD in the University of Cambridge, where he developed statistical approaches for analysing DNA copy number data. Upon completing his PhD in 2007 he moved to the University of Chicago, where he carried out post-doctoral research in the Department of Human Genetics. In Chicago, he focused on the analysis of RNA-sequencing data, developing novel methods that have become widely used in the field.

In 2010, he established his research group at the EMBL-European Bioinformatics Institute. His independent research has focused on understanding how differential gene expression is regulated between closely related species of mammals and in modelling variability in gene expression between single cells

John’s appointment in 2014 at the Sanger Institute enables his group to apply their computational approaches to novel biological questions through collaborations with faculty and research groups at the Institute.
