Part of EMBL-EBI's mission is to archive experimental data, supporting publications in journals and facilitating research reproducibility. The Gene Expression team, led by Robert Petryszak, comprises biologists, bioinformaticians and software engineers and is responsible for the acquisition, curation, quality control and user support for data submitted to the ArrayExpress archive of functional genomics experiments.
EMBL-EBI is commited to making archived data accessible to life scientists through resources such as the Expression Atlas, a value-added database of information on gene and protein expression patterns under different biological conditions. The Gene Expression team is responsible for acquiring high-quality microarray, RNA-seq and proteomics data from EMBL-EBI archives such as ArrayExpress and PRIDE, and from external sources. Our team provides in-depth manual curation, annotation to ontologies, quality control and re-analysis using in-house, standardised statistical pipelines. This allows us to provide accessible data visualisations in the Expression Atlas.
The Gene Expression team is also responsible for training and outreach for ArrayExpress and the Expression Atlas. We work closely with EMBL-EBI's Bioinformatics training programme to develop on-line training tools and deliver courses, workshops and conference presentations.
