Under the Directorship of Professor John O’Keefe, the Sainsbury Wellcome Centre for Neural Circuits and Behaviour (SWC) will bring together world-leading scientists to investigate how brain circuits process information to create the neural representations that guide behaviour. Developed through the vision and partnership of the Gatsby Charitable Foundation and the Wellcome Trust, and with substantial investment from these partners, the mission of SWC is to transform understanding of brain function. The Centre, located within UCL and close to its main campus in central London, is being structured to foster a culture of innovation, collaboration, enquiry and excellence. SWC scientists will use the latest advances in molecular and cellular biology, imaging, electrophysiology and behavioural techniques and enjoy an unparalleled research environment offering state-of-the-art research laboratories, cutting-edge scientific equipment, technologically-advanced prototyping and fabrication laboratories and custom in-house high-performance computing facilities. Commencing research operations in early 2016, SWC will comprise 12 highly interdisciplinary experimental research groups accommodated in a new, purpose-designed, seven-storey building. The Gatsby Computational Neuroscience Unit has relocated to the new building, facilitating broad and deep collaborations in data analysis and computational modelling. Scientists joining SWC will become part of UCL Neuroscience which brings together over 450 principal investigators offering extensive opportunities for interaction and collaboration. Formal teaching commitments will be minimal allowing scientists to focus on research. The Centre invites applications for SWC Senior and Principal Research Fellowships from outstanding, innovative, highly-motivated collaborative scientists with backgrounds in neuroscience as well as related physical and biological sciences. It is particularly interested in scientists wishing to extend the boundaries of technological development in areas such as high- density electrophysiological probes, telemetry, optical recording, molecular and genetic tools, new anatomical mapping techniques, and the use of virtual reality and other novel behavioural approaches such as video image analysis. Competitive salaries, tailored research space and generous relocation and recruitment packages, including research support, will be offered. Shortlisted fellowship candidates will be invited to a residential recruitment symposium scheduled for 18-20 November 2015.
