Research Interests:

  • Interstellar Medium of Ultra/ Luminous Infrared Galaxies (U/LIRGs)
  • Star-formation rates in U/LIRGs
  • Outflows of atomic gas, as traced by the (CII) 158μm line in local ULIRGs
  • Modelling the spectral energy distribution of galaxies and Active Galactic Nuclei (AGN)

I utilise multi-wavelength data in my research, however I have most experience working with infrared data (ISO, Spitzer and Herschel).
