PhD positions at the Center of Gravity, Copenhagen

The Center of Gravity at the Niels Bohr Institute (NBI) invites expressions of interest for a PhD fellowship in gravitational-wave theory and solutions to the relativistic 2-body problem under the supervision of Maarten van de Meent. The preferred starting date is Fall 2027. To receive full consideration, interested candidates should upload the material requested below before December 15th, 2026. The search will remain open until the optimal candidates are found.

Successful candidates will join the GWSKy project, funded by an ERC Synergy Grant. We are particularly interested in hiring creative and highly motivated candidates who can work collaboratively in a vibrant, welcoming, and synergistic group. The ERC-funded project called “Making sense of the unexpected in the gravitational-wave sky (GWSky)” is led by PIs Maarten van de Meent (NBI, Copenhagen, Denmark), Enrico Barausse (SISSA, Trieste, Italy), Zvi Bern (University of California, Los Angeles, US), and Alessandra Buonanno (Albert Einstein Institute, Potsdam). Given the synergistic aspect of the GWSky project, we anticipate the possibility of PhD students having a co-supervisor at one of the other nodes, and for them having the opportunity to have extended visits there.

The aim of the GWSky project is to use gravitational-wave measurements by existing and future observatories on the Earth and in space as precision laboratories for fundamental physics, cosmology, and astrophysics. This includes the current LIGO-Virgo-KAGRA detectors, as well as the future ground-based observatories Cosmic Explorer and Einstein Telescope, and the space-based detector LISA. By leveraging the PIs and their team’s expertise, the GWSky project aims to develop a groundbreaking framework capable of solving the highly nonlinear equations of Einstein’s General theory of Relativity, creating waveform models with unprecedented accuracy, and translating these results into practical tools for interpreting the data.

More information can be found on the website: https://gwsky.org/

Possible topics include: development of gravitational self-force methods at second order in the mass-ratio; incorporation of environmental and/or beyond GR effects in the self-force formalism; and utilization of self-force data to enhance effective-one-body waveform models.

The Center of Gravity (CoG) is a center for new ideas about the foundations of physics. We bring together cutting-edge research in observations of black holes and in the formal theory of relativistic and quantum aspects of gravity, completing the visions of Bohr and Einstein for the gravitational interaction. Our research endeavor spans from data analysis to theoretical disciplines within astrophysics and high-energy physics, and we aim to drive gravitational-wave physics to an exciting future. We have our physical home in the beautiful and legendary building at Blegdamsvej 17, established by Niels Bohr. This is the place where quantum theory was born and where many exciting new developments in gravity are now taking place. Today, the Niels Bohr Institute carries an important legacy in physics and is one of the leading institutes in theoretical and experimental physics. At the Center of Gravity, we hope to carry on the pioneering spirit that has defined our predecessors at the Niels Bohr Institute through trailblazing and fundamental research. More information can be found on the website: https://the-center-of-gravity.com/ The University of Copenhagen wishes to reflect the diversity of society and welcomes expressions of interest from all qualified candidates regardless of personal background. PhD students at the University of Copenhagen receive a competitive salary (including pension) and funds for travel and computing. Generous parental leave, state-subsidized childcare, vacation, and full medical care are provided to employees in Denmark.

Operation Director for SCIENCE Makerspace University of Copenhagen

We invite applications for a 5-year position as Operation Director for the SCIENCE Makerspace at the Faculty of Science, University of Copenhagen. The Faculty of Science is committed to sustainably continuing the Makerspace activities at the end of the 5-year period, providing the possibility for extending the position long-term.

About the SCIENCE Makerspace

We are establishing a top-tier Makerspace at the Faculty of Science, University of Copenhagen, spearheaded by the Department of Computer Science (DIKU), Niels Bohr Institute (NBI), and the Department of Science Education (IND). The SCIENCE Makerspace vision is built upon a foundation of Diversity, Equity, Inclusion, and Belonging (DEIB) and aims to create an inclusive learning environment that bridges disciplines, supports different ways of learning, and attracts students with diverse backgrounds and interests. Everyone is welcome, and no prior knowledge of makerspaces, machines, or materials is required.

The SCIENCE Makerspace will be established as a 600 sqm facility centrally located at Nørre Campus, with a budget of 42 million DKK over 5 years supported by the Novo Nordisk Foundation. The Makerspace is expected to host 1-3 university courses per academic quarter, independent projects for BSc/MSc/PhD students, and be a venue for extracurricular workshops and ‘blue sky’ ideas from faculty and students. The Makerspace will also facilitate the integration between traditional and non-traditional forms of knowledge production within an Expert-in-residence program.

The Faculty of Science at the University of Copenhagen is one of Scandinavia’s largest science faculties, with over 4,000 staff, ~9,000 students, and an annual turnover exceeding DKK 3 billion, located in the heart of Copenhagen. SCIENCE hosts 12 departments spanning a breadth of disciplines from molecular biology and chemistry to mathematics, computer science, and geoscience, united by a commitment to curiosity-driven, high-impact research.

Description of the position

We offer a unique opportunity for you to become the Operation Director of the ‘yet-to-be-build’ 600 sqm SCIENCE Makerspace centrally placed at the Northen Campus in Copenhagen. The SCIENCE Makerspace vision is to design, build and run an inclusive and innovative learning space that bridges disciplines, allows for multi-modal learning activities, and attracts a diversified and balanced cohort of students from different educational programs (BSc, MSc, PhD) across the 12 Departments.

The Operations Director will direct the SCIENCE Makerspace and be the manager for the Makerspace team. The Operation Director is responsible for ensuring that principles for DEIB are mainstreamed in all decisions in the Makerspace.

You will be part of the core decision-making on how to organize, establish, and run the ‘one-of-a-kind’ Makerspace. You will collaborate with committed faculty from DIKU, NBI, and IND in the establishing phases, and with the Deanery for Education for long-term engagement across the departments in making the Makerspace vision a reality.

You will be part of hiring the team who will run the makerspace together with you including Technical Lab Manager, Lab Technician, and a group of student mentors.

This is a unique opportunity to be part of creating something new, in the largest university in Denmark, which fundamentally will change how we organize teaching and learning at the SCIENCE departments.

You will need four core competences to succeed in the position:

  1. You will need skills and expertise which allow you to strategize and develop ideas which will foster success for the SCIENCE Makerspace vision. This includes the work of identifying and understanding upcoming challenges for e.g. DEIB [DK3] (organizationally, socially, technically, and spatially) and finding solutions, while pro-actively execute required actions. Further, the Operation director must be able to function within an ‘entrepreneurial atmosphere’ where everything is not settled yet.
  2. You will need leadership and management competences which will allow you to lead a mixed Makerspace team of both highly skilled lab manager and lab technicians whose work requires levels of trust and autonomy, as well as student mentors who need clear instructions and guidance.
  3. You will need to navigate and understand the organizational and social structures of academia and university life, this includes considering the intrinsic motivation of researchers/teachers and PhD students, and how they might differ for MSc/BSc students. Such competence can arrive from your own experience during your education and does not require that you have worked in a university setting previously.
  4. You need interest in ‘making’ and Makerspaces. Furthermore, it is important that you consider consulting relevant experts about their views and perspectives, which will allow you to take qualitatively and well-founded decisions about our joint Makerspace.

You will not be a one-person army, instead you will have three main groups with different types of competences and experiences you can draw on in the position, including the Makerspace team, an experienced team of administrative management colleagues, and the Faculty of SCIENCE teaching committee.

Two Postdoctoral Positions in Joint Simulation-Based Inference for Large-Scale Structure and High-Energy Astrophysics at CNRS, LAPTh

The Laboratoire d’Annecy de Physique Théorique (LAPTh) invites applications for two postdoctoral positions within ADACSI (Accelerating Discoveries in Astrophysics and Cosmology with Simulation-based Inference), funded by the Multidisciplinary Institute for Artificial Intelligence (MIAI) through an AIforScience Research Chair.

ADACSI will develop a multi-probe simulation-based framework for the joint analysis of large-scale structure (LSS) and gamma-ray data. By combining these complementary probes of the same underlying matter distribution, the project aims to sharpen constraints on astrophysical source populations and dark-matter signals, exploiting statistical correlations across datasets to break degeneracies that limit single-probe analyses. The framework will be validated on synthetic data and applied to public datasets, e.g. Fermi-LAT and DESI.

The two postdocs will be recruited simultaneously and will work as a team toward a single joint pipeline.

Position 1 — LSS forward modelling and SBI methodology. Developing fast simulations of the LSS observables, in particular data from spectroscopic galaxy surveys and CMB lensing and the inference machinery, building on and extending the SimBIG pipeline. This forward model is also the baseline for the gamma-ray side of the project.

Position 2 — Gamma-ray astrophysics and data analysis. Modelling how gamma-ray emitters populate the cosmic web and linking source populations to the underlying halo and galaxy distribution; developing SBI pipelines for Fermi-LAT data, first standalone and then jointly with LSS.

Qualifications. A PhD in astrophysics, cosmology, or a related field completed by the start date; strong programming skills; working knowledge of machine learning applied to astrophysics and cosmology, in particular simulation-based inference. For Position 1, experience with LSS simulations and analysis, and ideally galaxy redshift surveys and HPC. For Position 2, experience with gamma-ray data analysis and its astrophysical interpretation. Applicants with a strong machine-learning or statistics background moving into astrophysics are welcome.

Supervision and environment. Both positions will be co-supervised by Dr. Azadeh Moradinezhad and Dr. Francesca Calore, within the Astroparticle and Cosmology group at LAPTh (astrocosmolapth.com). External collaborators include Christoph Weniger (GRAPPA, University of Amsterdam) and Francisco Villaescusa-Navarro (Flatiron Institute, New York), as well as SimBIG collaboration. A PhD student and several Master’s students will also be recruited within ADACSI, offering co-supervision opportunities. The positions provide access to CNRS/LAPTh computing resources and generous travel support and, as an MIAI-funded chair, connect the postdocs to the institute’s interdisciplinary AI community; the group also benefits from its proximity to the University of Geneva and CERN.

Terms. Position 1 is a two-year appointment; Position 2 is a three-year appointment. Salary on the USMB scale, commensurate with experience, including social security and health coverage. The expected start date is 1st October 2027with some flexibility.

Applications. Submit via AcademicJobsOnline:

  1. a cover letter, indicating Position 1, Position 2, or both;
  2. a CV with a list of publications;
  3. a research statement (up to four pages);
  4. three letters of recommendation, arranged by the applicant.

Applications received before November 20th – 2026 will receive full consideration; the positions remain open until filled. Shortlisted candidates will be invited to a remote interview.

Contact. Dr. Francesca Calore (francesca.calore(at)lapth.cnrs.fr) and Dr. Azadeh Moradinezhad (azadeh.moradinezhad(at)lapth.cnrs.fr)
