Spectroscopic analysis of cool giants and supergiants
  Cool red giants and supergiants are among the most complex and fascinating stars in the Universe. They are bright and large, and thus can be observed to enormous distances allowing us to study the properties of their host galaxies, such as dynamics and chemical abundances. This review lecture addresses various problems related to observations and modelling spectra of red giants and supergiants.
