Personal profile
Research overview
I currently do research in Astrophysics, education and inclusion.
My astrophysics research focuses on exploring large spectroscopic galaxy redshift surveys, which collect spectra for millions of galaxies in the near and distant Universe. I use these to learn not only how galaxies themselves have evolved, but also to understand the content, geometry and expansion history of the Universe. Currently I'm particularly interested in understanding how knowing more about the evolution of galaxies can help us derive more robust information about the evolution of the Universe as a whole, and specifically the role of the cosmic web in that context. I'm a member of SDSS-III, SDSS-IV, VIPERS, GAMA and DESI.
My education research focuses on the impact of professional development sessions for secondary school physics in Scotland, and the role of current astronomy research and research data in that context.
My inclusion research focuses on attitutes towards inclusion in higher education, the hidden curriculum, and literacy in STEM subjects.
