Bryan's career has taken him from his native New Zealand where he studied for his undergraduate and PhD degrees at the University of Cantebury, to the University of Oxford, the Rutherford Appleton Laboratory and back to New Zealand before he returned to the UK in 2000, initially, to take up the role as head of BADC, and eventually Director of the newly created CEDA.

Over the years Bryan has built up an international reputation not only for his atmospheric and climate science, but also for his widely acknowledged experience in all aspects of data management, metadata and curation. Bryan brings these skills to the wider community through involvement in numerous boards and steering committees, as well as travelling widely on the international circuit to give seminars and key note presentations.

Bryan's maintains a blog covering all aspects of data management and NWP development. 

Sam Pepler - Head of Curation

Photo of Sam PeplerSince joining the British Atmospheric Data Centre Sam has developed a portfolio of curation knowledge and experience that had lead him to his present role with CEDA. His pricipal role is to oversee all operational aspects covering the data curation role of CEDA - both overseeing the hardware aspects and work required for proper curation of data (i.e. metadata content and services).

Sam is also regularly called upon by wider groups within NERC to assist in the continued improvement of curation practices across all of NERC data centres.

Sam is also responsible for initial curation cost estimates for activities looking to use CEDA as a curation centre for their research outputs.

Martin Juckes - Head of Science and Head of BADC

Photo of Martin JuckesMartin joined the BADC in 2001 following a series of positions in Colorado (88-90), Reading (90-93), Munich (93-99) and Oxford (99-01) during which time he has published on stratospheric and tropospheric dynamics, baroclinic waves, the dynamics of the tropopause, data assimilation and paleo-climate temperature reconstructions. These positions have been a natural career progression for Martin following his degree and PhD (on stratospheric dynamics) obtained from Cambridge.

As head of atmospheric science for CEDA, Martin ensures that CEDA data services reflect and move with the needs of our designated user community. The immediate challenge is to deliver, in collaboration with European partners, the European component of the archive for the CMIP5 project; this archive will underpin much of the science that goes into the next assessment of the Intergovernmental Panel on Climate Change.

Andrew Harwood - Infrastructure Manager 

Photo of Andrew HarwoodAndrew joined STFC's predecessor, "SERC" - the Science and Engineering Research Council, in 1988 holding a degree in physics (York) and an MSc in Medical Physics and Information Technology (Aberdeen). He worked for several years on various space projects, including the Infra-red Space Observatory and the original ill-fated Cluster mission. His main role in these projects was to develop software for the EGSE (Electronic Ground Support Equipment) and later to process the science data returned.

Ten years later, following his foray into satellites, Andrew brought his skill to the BADC during its early years and was instrumental in developing some of its basic software infrastructure. As our infrastruture manager Andrew has the responsbility for the basic software services of CEDA which he continues to develop and improve.
