Research Areas

Interstellar medium
Circumstellar medium
Star formation


Research Interests

My main research areas are:

  • carbonaceous molecules and dust (Polycyclic Aromatic Hydrocarbon molecules, fullerenes, carbonaceous dust)
  • galactic and extra-galactic star forming regions
  • the interstellar and circumstellar medium

Most of my research is based on infrared spectrocopy and imaging with ground-based and space-born telescopes.

I am always looking for new graduate students, so if you're interested in doing a Master's or PhD project in one of these fields, please contact me.
