I am an RSE based in an academic institute (BP Institute) in the University of Cambridge. We have academics from Maths, Earth Sciences, Engineering, Chemistry and Chemical Engineering. My fellowship has been based around development of a widely-used open source physics and engineering software package called FEniCS, which I work on with members of the Engineering Dept in Cambridge, and other international contributors. Community building has also been an important part of my fellowship, and I have worked hard to sustain a local RSE seminar series, an annual meeting, and a network connecting departmental RSEs and centrally funded RSEs in the university. My fellowship will be coming to an end next year, but I have secured a change in my post description, and I will continue to work in the same way, but probably with more emphasis on securing funding opportunities for future RSE work.
