Forskning

I am an observational astrophysicist working both with general galactic chemical evolution trying to understand where and how different elements form on a cosmic scale, and with galactic archeology trying to understand how different parts of our galaxy — and hence galaxies in general — have formed. The method of investigation that I use in my research is high resolution stellar spectroscopy, most often of red giant stars. I have specialized in near-infrared observations (H- and K-band, around 1.5 and 2.3 microns), but I have also worked with optical and mid-infrared data. As the Deputy Survey Scientist of the APOGEE survey, I am heavily involved in the analysis of the APOGEE H-band spectra.
