PhD fellowships at SISSA in Trieste

The gravitational-wave physics group at SISSA (Trieste, Italy) invites applications for PhD positions in gravitational-wave theory, source modeling, science interpretation and data analysis, to start in the fall of 2026. The hard deadline for applications is 23-02-2026 13:00 local Italian time.

Successful candidates will join the GWSKy project, which an ERC Synergy Grant has recently funded. We are particularly interested in hiring creative and highly motivated candidates who can work collaboratively and independently 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 Enrico Barausse (SISSA, Trieste, Italy), Zvi Bern (University of California, Los Angeles, US), Alessandra Buonanno (Albert Einstein Institute, Potsdam) and Maarten van de Meent (Niels Bohr Institute, Copenhagen, Denmark).

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.

As a consequence, at SISSA we are looking at candidates in the following research areas: numerical-relativity simulations in General Relativity and alternative theories of gravity; environmental effects for binary systems; tests of General Relativity; gravitational-wave data analysis and machine learning; waveform modeling.

Applications should be sent via https://pica.cineca.it/sissa/phd-agp-01-2026 Please tick both the “SISSA fellowship” and “ERC – GWSky fellowship” options within the platform when you apply

Multiple funded PhD positions available at the U²GRC

Multiple funded PhD positions are available at the UMass Dartmouth and University of Rhode Island gravity research group. 
We seek candidates for multiple, fully-funded PhD positions at UMass Dartmouth and the University of Rhode Island in the broad area of gravitational-wave science.

Gravitational physics researchers at both universities have recently established the UMass-URI Gravity Research Consortium (U2GRC) — a joint gravity research group. Several new researchers have been hired by both universities, including Drs. Aidan Chatwin-Davies (URI), Sarah Caudill (UMassD), Derek Davis (URI), Deborah Ferguson (URI), Michael Puerrer (URI) and Vijay Varma (UMassD). This is in addition to others who were already present, i.e. Drs. Rob Coyne (URI), Scott Field (UMassD), Bob Fisher (UMassD), Doug Gobeille (URI), and Gaurav Khanna (URI/UMassD). Most are members of the LIGO-Virgo-KAGRA Collaboration, LISA Consortium and the SXS Collaboration. U2GRC currently has over 20 PhD students working on various different aspects of gravitational-wave science. The group has Zoom meetings twice a week and meets in person monthly. Course exchange agreements have been formalized between the two universities to make it seamless for U2GRC students to take classes being offered at either campus. Additional agreements underway include joint student advising, collaborative grant funding, and extensive computational resource sharing.

We are particularly interested in applicants interested in working in these specific research areas: gravitational-wave data analysis and detector characterization, data driven surrogate models, numerical relativity, black hole perturbation theory, and quantum information / gravity. Please apply by February 1st, 2026 for best chances of receiving funding.

The ERC-funded project called “Making sense of the unexpected in the gravitational-wave sky (GWSky)” is led by PIs Alessandra Buonanno, head of the ACR department, Enrico Barausse (SISSA, Trieste, Italy), Zvi Bern (University of California, Los Angeles, US), and Maarten van de Meent (Niels Bohr Institute, Copenhagen, Denmark). Given the synergistic aspect of the GWSky project, we anticipate that for a few postdoctoral scholars, there will be the opportunity to spend two years at the AEI and the subsequent two years in another node. One of the supervisors of the Ph.D. students at the AEI may be located in another node.

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 groups’ expertise, the GWSky project aims to develop a groundbreaking framework capable of solving the highly nonlinear equations by Einstein’s General theory of Relativity, creating waveform models with unprecedented accuracy, and translating these results into practical tools for interpreting the data.

As a consequence, we are looking at candidates in the following research areas: post-Minkowskian formalism, scattering amplitudes, gravitational self-force, post-Newtonian theory, effective-one-body formalism, numerical-relativity surrogate models, methods to accelerate waveform generation, numerical-relativity simulations in General Relativity and alternative theories of gravity, environmental effects for binary systems, tests of General Relativity, gravitational-wave data analysis and machine learning.

To apply, please submit your application via our job portal
