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).


  • D.Phil (PhD) in Astrophysics - to present - University of Oxford (Linacre College)
    • Thesis title: The Inter-Stellar Medium and Physical Properties of Infrared Galaxies
  • MSci (Masters in Physics) - 2007 - Durham University (University College)
    • Masters title: Very High Energy Gamma Rays from the Active Galactic Nucleus PKS 2155-304

About Us

The AHPC group was established in 2012 and carries out pioneering work in Astrophysics and Parallel and Distributed Computing.

The group has a prestigious network of international collaborators and is directed by Prof. Andreas Efstathiou, Vice Rector for Research and External Affairs.
