Research Interests:

Darek Lis's research interests include high-resolution molecular spectroscopy of solar system objects and the interstellar medium, from the Milky Way to the high-redshift Universe. Using ground-based and space-borne far-infrared facilities, such as the Caltech Submillimeter Observatory, Herschel Space Observatory, or Stratospheric Observatory for Infrared Astronomy he has studied molecules and their isotopic ratios to understand the physical conditions and chemistry of the interstellar medium, as well as the origin of Earth's oceans.
