Scientific interests:

  • Stellar populations in different environments
  • Dwarf galaxies
  • Nuclear star clusters
  • Globular clusters

Skills and techniques:

  • Star formation histories from integrated light spectra
  • Chemo-dynamical evolution of galaxies
  • Stellar chemical abundances
  • Stellar kinematics and dynamics
  • Bayesian statistics and mixture modelling

At the AIP I am a member of the "1001 Magellanic Clouds" 4MOST spectroscopic survey and support the development of this future VISTA instrument. In addition, I work on modelling the dynamics of the Large Magellanic Cloud using equilibrium dynamical models.

My GitHub account contains some codes with more general use that I have developed: GitHub
