Research

Galaxy evolution

  • The quenching of star formation
  • The role of internal and external processes in galaxy evolution
  • The evolution of galaxy scaling relations across cosmic time

Chemical enrichment and the interstellar medium

  • The stellar metallicity of star-forming, green valley and passive galaxies
  • Analytical modelling of the evolution of the gas and chemical content of galaxies

Large spectroscopic galaxy surveys

  • Optical/NIR single-fiber spectroscopy (e.g. SDSS-II)
  • Integral field spectroscopy (e.g. SDSS-IV MaNGA)
  • Spectral fitting of stellar continuum and emission-lines with pPXF and FIREFLY
