PhD and Postdoc Openings in Astrophysics, Planetary Science, and Protoplanetary Disk Chemistry University of Copenhagen in Denmark

University of Copenhagen / Niels Bohr Institute is recruiting two PhD fellows and one postdoctoral researcher in Astrophysics, Planetary Science, Protoplanetary Disks, and Astrochemistry.

PhD project 1: Disks around very low-mass stars and brown dwarfs, using ALMA observations and modelling of elemental/isotopic ratios (C/O, D/H, etc.), with an emphasis on connecting observations and theory.

PhD project 2: Ices in disks around solar-type stars, using JWST observations and radiative transfer modelling, with interest in vibrational spectroscopy and ice chemistry.

Postdoc project: ALMA/JWST observations of planet-forming disks, with preparatory work for ELT/METIS and potentially PRIMA. The postdoc may lead projects, supervise students, and help shape future research directions.

The positions are hosted in the Young Stars and Planet / Astrophysics and Planetary Science section at the Niels Bohr Institute, University of Copenhagen, in the New Niels Bohr Building, Copenhagen, Denmark. The group works on star and planet formation, protoplanetary disks, and astrochemistry, combining observations from major facilities with theoretical and numerical modelling.

Eligibility highlights: PhD applicants should have a master’s degree equivalent in a relevant field such as physics, chemistry, or biology; experience in astronomical data analysis, radiative transfer, or numerical modelling is an advantage. Postdoc applicants need a PhD in astronomy, astrophysics, or a related field, plus strong data-handling skills, Python coding, teamwork, and excellent English.

Funding and terms: The PhD positions are 3-year full-time fellowships under the regular PhD programme (5+3 scheme). The postdoc is a 2.5-year fixed-term position. The group is supported by the Carlsberg Foundation and Villum Fonden; the postdoc salary starts at about 35,000 DKK/month plus pension under Danish academic agreements.

Application window: Deadline is 26 May 2026. Applications must be submitted online in English through the University of Copenhagen portal.
