Nils Ryde

I am Office director for Astrophysics and Topic Responsible for Astronomy and Astrophysics at Lund Universtiy.

My field of research is stellar spectroscopy. My main interests deal with the origin of the inner bulge of the Milky Way and the Galactic Center regions.  This is performed by investigating 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.
