My field of research is stellar spectroscopy. My main project now deals with the origin of the galactic bulge by investigating its stars at high spectral resolution in the near-IR. A red thread through my research projects have been spectroscopy at high resolution with special emphasis on the opportunities that come with cutting-edge IR spectrometers.

Galactic Chemical Evolution

    1. Assembly history of the Nuclear Star Cluster with KECK/NIRSPEC and DCT/IGRINS
    2. Origin of the inner Galactic bulge, |b| < 3 degrees with VLT/CRIRES/ISAAC/UVES, NTT/SOFI, and KECK/NIRSPEC
    3. Chemical evolution of fluorine, sulfur, and carbon in the Milky Way with VLT/CRIRES/UVES
Stellar atmospheres, investigated by means of infrared spectroscopy
    1. Water vapor in the atmospheres of Red Giants with Gemini/TEXES, SOFIA/EXES
    2. The Mg I lines emission at 12 microns, Gemini/TEXES
    3. Outer atmospheres and winds of red giant star with Gemini/Phoenix, ISO/SWS/LWS
Development of Infrared Spectroscopy with the help of laboratory measurements
    1. Near-IR Atomic and Molecular Spectroscopy in the Laboratory with the Edlen laboratory
    2. IR spectroscopy at high spectral resolution for the E-ELT
