My main research interests are galaxy evolution, with a focus on the multiwavelength properties of both local and distant galaxies. I use the Herschel Space Observatory in combination with UV-optical data from large photometric and spectroscopic galaxy surveys such as GAMA and MaNGA to determine the star-formation histories and dust properties of large samples of galaxies.
My research interests include:
- Multiwavelength spectral energy distribution (SED) model fitting.
- Statistical interpretation of galaxy properties derived from large spectroscopic and multiwavelength photometric surveys.
- Galaxy bimodality - starbursts, galaxy mergers, post-starburst galaxies, quenching.
- Connection between galaxy morphology and physical properties.
- Properties, origins and evolution of dust and gas in galaxies, particularly in (traditionally gas/dust-poor) early-type galaxies.
- Chemical evolution modelling.
Why do galaxies stop forming stars?
My research focuses on post-starburst galaxies which are thought to be caught in the act of transformation between star-forming and quiescent Post-starburst galaxies are commonly assumed to be devoid of gas and dust, although recent studies (e.g. Rowlands et al. 2015) showed that post-starbursts still harbour a significant gas reservoir, comparable to those of star-forming galaxies. Post-starburst galaxies in the local Universe are not red-and-dead as previously thought. My research aims to address what role do post-starbursts really play in the formation of quenched galaxies.
I am a postdoc at the Johns Hopkins University working with Tim Heckman, Nadia Zakamska and Brice Menard on the MaNGA survey.
I previously worked at University of Andrews with Vivienne Wild on the ERC starting grant SEDmorph project to study the physical properties of galaxies and how these change over time.
I completed my PhD at the University of Nottingham in June 2013, where I worked on the dust properties of galaxies using Herschel-ATLAS data.
