Dr Sarah Callaghan is a senior scientific researcher and project manager for the British Atmospheric Data Centre, at STFC Rutherford Appleton, UK. She currently project manages the NERC Data Citation and Publication project, which is a cross NERC Data Centre project which aims to develop the mechanisms for the citation and publication of datasets.  She is also a co- chair of the CODATA-ICSTI Task Group on Data Citations, a member of the DataCite Working Group on Criteria for Datacentres, and an associate editor for the scientific journal Atmospheric Science Letters, with a particular aim of developing the processes for data publication. She has experience of both creating and managing large datasets, and so understands well the frustrations that scientists can experience as a result of dealing with data!
