We lead the development of Expression Atlas, a flagship open-access resource integrating bulk and single-cell transcriptomics data across species, tissues, and conditions.

We promote FAIR data principles and support data reuse through the coordinated submission and expert curation of functional genomics datasets, ranging from bulk and single-cell RNA-Seq to epigenetic profiling technologies. Submissions are managed via the Annotare submission tool and archived in the BioStudies database as part of the ArrayExpress collection. Through standardised metadata capture, we ensure that submitted datasets are made discoverable, well-annotated, and ready for integration into downstream resources such as Expression Atlas.

With combined expertise in biology, bioinformatics, and software engineering, we focus on:

• Metadata enrichment and quality control
• Scalable, reproducible analysis pipelines
• Accessible visualisations
• Development of community standards and formats
• Outreach and training to support open science

We also support the data infrastructure of the Human Cell Atlas (HCA) by maintaining the HCA Data Repository. We manage the ingest of new datasets through the HCA Data Contributor Portal, working with contributors and HCA bionetworks to ensure data are archived in the HCA Data Portal according to agreed metadata standards. We lead coordination efforts to evolve these standards in response to emerging technologies and the needs of integration teams building the atlases.
