I investigate the formation and evolution of the Milky Way through the characterisation and analysis of the chemical distributions of its stars.
I pursue research in the field of Galactic Archaeology, which seeks to unravel the formation and evolution history of the Milky Way. I do this using a variety of astronomical data including spectra, photometry and asteroseismology.Key projects in which I am involved that further this investigation are:* Statistical analysis of chemical abundance distributions in stellar populations using techniques such as Principal Component Analysis (PCA), Bayesian Inference and t-distributed stochastic neighbor embedding (t-SNE).* Galactic Chemical Evolution studies with chemical yields compared to big observational datasets* Automated determination of stellar parameters and chemical abundances* Characterisation of binary systems* Detailed stellar parameter and chemical abundance analysis of benchmark starsI'm an active member of 4MOST and WEAVE, which are large scale multi-object spectrographs on the 4m telescopes, VISTA@ESO in the southern hemisphere and WHT@ING in the northern hemisphere respectively. With the high and medium resolution spectra from both projects will characterising to never before detail the chemical distribution within the Milky Way.A critical mission that has significantly advanced our understanding of the Milky Way is the ESA Gaia mission which is measuring precise positions and motions of over 1 billion stars in the Milky Way. Combining the kinematic with chemical information from these projects will result in a chemico-kinematic, multi-dimensional chart of the Milky Way against which to test our theories of galactic formation and evolution.
