Dr Sarah Rogers has been the Instrument Responsible for Sans2d at ISIS-STFC, since May 2010. She has been a facilities scientist on small-angle beamlines since August 2006, firstly as a junior beamline scientist on I22 at Diamond Light Source (DLS) Ltd and later joining ISIS as a member of the SANS team in February 2008. Before arriving at Diamond she was at the University of Bristol in the School of Chemistry, where she was undertaking an EPSRC funded PDRA position in the lab of Professor Julian Eastoe, studying the formation of gold nanoparticles in supercritical carbon dioxide. Prior to this she completed her PhD, titled ‘Fluorocarbon-Hydrocarbon Incompatibility in Micellar Polymerizations’, in the same lab in 2005. During her PhD she also was involved in many other projects including water-in-supercritical CO2 microemulsions, ionic liquid-in-oil microemulsions, novel surfactant synthesis and characterization and pH-degradable surfactants. Sarah also obtained her MSci in Chemistry from the University of Bristol in 2002.

Sarah also has a keen interest in the design and implementation of beamline sample environment such as stopped-flow cells for the study of kinetic experiments, the grazing incidence small-angle scattering (GISAS) set-up which allows in-plane structure on the nanometre lengthscale to be studied and pressure cells for the study of supercritical fluids. Her expertise in this field led to her becoming a co-investigator on a STFC Facility Development Grant (in collaboration with DLS Ltd and Imperial College London) to develop pressure-jump apparatus for time-resolved X-ray diffraction13.
