I lead the development of scientific instrumentation and facilities for ground- and space-based astronomy from the ultraviolet to the near-infrared, with a particular emphasis on future missions. I am Principal Investigator for the UK ELT instrumentation programme, as well as Project and Instrument Scientist for MOSAIC, the multi-object spectrograph for the ELT. I lead the UK's participation in the CASTOR UV space mission. My research programme revolves around galaxy evolution, with a focus on low-mass galaxies and star cluster systems in the nearby Universe.
