Tag: PhD position

The Laboratoire d’Annecy de Physique Théorique (LAPTh, CNRS/Univ. Savoie Mont Blanc) invites applications for one postdoctoral position in theoretical physics, with research opportunities in quantum gravity, cosmology, and AI for Science, and additional connections to the Physics of Learning.

The main project investigates connections between fundamental theory and cosmology, with particular interest in accelerated expansion and the origin of dark energy within string theory and M-theory. It combines analytical approaches with the application and development of Machine Learning methods for solving the equations of motion governing compactifications.

There will also be opportunities to work on the Physics of Learning, whether to understand and improve learning algorithms in their own right or to feed back into the physics applications, using methods from physics to study, for example, the dynamics of optimization and sampling, the theory of neural networks, and neural scaling laws. The successful candidate will be encouraged to develop their own independent research program alongside collaborative work within the project.

Qualifications: Applicants must hold, or expect to obtain by the starting date, a PhD in theoretical physics or a closely related field. We welcome candidates with a strong theoretical physics background and research interests relevant to one or more of the project’s directions. Experience with AI and machine learning is welcome but not required. Knowledge of French is not required.

Research Environment: The successful candidate will join the Mathematical Physics group at LAPTh and work with Dr. G. Bruno De Luca. A PhD student will be recruited at the same time, offering the opportunity to contribute to their supervision and help develop a growing research team.

The project is funded by the Multidisciplinary Institute for Artificial Intelligence (MIAI Cluster), offering interactions with researchers in fundamental physics, mathematics and AI. Existing contacts with researchers in the Simons Collaboration on the Physics of Learning provide further opportunities for scientific exchange. The position provides dedicated computing resources and support for conferences and research visits. The laboratory is located in Annecy, in the French Alps, about 45 km from Geneva, with proximity to CERN offering further opportunities for exchange and collaboration.

Terms of Employment: The appointment is for three years, with an anticipated start date in September 2027 and some flexibility possible. Salary will follow the USMB scale and be commensurate with experience. The appointment includes the usual social benefits.

Application Procedure: Interested candidates are invited to apply in English via AcademicJobsOnline, including:

(i) a cover letter;
(ii) a CV with a list of publications;
(iii) a research statement describing past work and future research interests;
(iv) at least three recommendation letters submitted directly by the referees.

Applications, including recommendation letters, received by 18 December 2026 will receive full consideration. The position will remain open until filled. Shortlisted candidates will be invited to a remote interview.

GRAPPA invites applications for one or more PhD positions to work at the interface of general relativity, gravitational wave astrophysics, and dark matter phenomenology within the ERC Advanced Grant “De Tenebris,” led by Prof. G. Bertone.

The PhD candidate will develop and apply theoretical and computational models for compact binaries in astrophysical/dark matter environments and contribute to the interpretation of current and future gravitational wave observations (LISA and next-generation ground-based detectors). The position is embedded in a collaborative team with strong ties to the international gravitational wave and dark matter communities.

We are looking for candidates who: – will have completed an MSc in Physics, Astronomy, or a closely related field by the start date; – have a solid grounding in general relativity and/or gravitational wave astrophysics; – have experience in scientific programming (e.g., Python or C++); – can communicate clearly in English and enjoy working in a collaborative research environment. It is a plus—not a requirement—if you are familiar with cosmological or N-body simulations, gravitational wave data analysis, or dark matter phenomenology.

GRAPPA is the center of excellence in gravitation, astroparticle physics, and cosmology at the University of Amsterdam, located at Amsterdam Science Park, with a lively seminar culture and close connections to the LIGO/Virgo/KAGRA, LISA, and Einstein Telescope collaborations.

The University of Amsterdam is an equal-opportunity employer. We are committed to building a diverse, inclusive community and welcome applications from all qualified candidates.

How to apply

Applications should be submitted via AcademicJobsOnline. Please include:

• a cover letter;
• your CV, including a list of publications (if any);
• a brief statement of research interests;
• two letters of recommendation.

The expected start date is between Spring and Fall 2027. Application Deadline: 1 December 2026.

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.
