Jes K. Jørgensen

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.

The Niels Bohr Institute at the University of Copenhagen is advertising multiple opportunities in astrophysics , planetary science , astrochemistry , and related research areas. Openings included in this post: • Half-Time Science Communicator and Project Administrator for the OceanNexus project, an interdisciplinary Horizon Europe project focused on climate tipping points in the ocean, marine ecology, society, and Earth system modelling. • Postdoc in Astrophysics and Planetary Science working on the chemical composition of protoplanetary disks, life-enabling molecules, JWST and ALMA observations, and preparation for future infrared facilities. • Two PhD fellowships in Astrophysics and Planetary Science focused on the chemistry of planet formation, interstellar ices, complex organic molecules, star and planet formation, and astrochemical evolution. Research themes and methods: observational astrophysics, infrared and sub-millimeter spectroscopy, JWST, ALMA, protoplanetary disks, radiative transfer, numerical modelling, astrochemistry, laboratory ice spectra, and science communication/project administration. Institution and environment: The positions are hosted at the Niels Bohr Institute , University of Copenhagen , in a collaborative and international research environment. The PhD projects are linked to the Astrophysics and Planetary Science section and, in one case, the Villum Young Investigator project “Chemistry meets Astrophysics: pathways to life-enabling ingredients during planet formation”; another set is part of the Center for Interstellar Catalysis. Eligibility highlights: The postdoc requires a PhD in astronomy, astrophysics, or a related field, plus strong data-handling and Python skills. The PhD fellowships require a degree equivalent to a Danish master’s degree in physics, chemistry, biology, astrophysics, astrochemistry, planetary science, or related fields. Experience with astronomical data analysis, radiative transfer, numerical modelling, or astrochemistry is advantageous. Funding/employment: The postdoc is a 2.5-year fixed-term full-time academic position with salary and pension. The PhD fellowships are full-time for up to 3 years under the regular PhD programme (5+3 scheme), with salary and pension according to Danish academic agreements. Application window: Deadlines are 22 May 2026 for the science communicator/project administrator role, 26 May 2026 for the postdoc and one PhD call, and 27 May 2026 for the other PhD call.
