The award supports my work building the Hyperboloidal Research Network, a geographically distributed community working on hyperboloidal and asymptotic methods in relativity. This is a joint effort with David Hilditch, Rodrigo Panosso Macedo, and Alex Vañó-Viñuales.

I draw on my earlier experience coordinating KI-Net, a research network in kinetic theory. Our community website brings together researchers, events, and shared learning materials.

Workshops

We have organized three workshops bringing together mathematical relativity, numerical relativity, and gravitational-wave physics:

  • Infinity on a Gridshell, July 10–13, 2023, at the Niels Bohr Institute in Copenhagen. The inaugural workshop covered black-hole perturbation theory, analysis of wave equations, and nonlinear Einstein equations.
  • Virtual Infinity Workshop, July 1–2, 2024, held online, with short research talks and discussions aimed at developing collaborations.
  • Hyperboloidal Foliations and their Application, January 12–16, 2026, at the Erwin Schrödinger Institute in Vienna, connecting geometric analysis with applications to gravitational radiation.

Topical Collection

Our topical collection in General Relativity and Gravitation, Hyperboloidal foliations in the era of gravitational-wave astronomy: from mathematical relativity to astrophysics, contains 17 published articles, including our editorial published on September 12, 2025. The collection is now closed for submissions.

David Hilditch, Rodrigo Panosso Macedo, Alex Vañó-Viñuales, and I served as guest editors. The collection grew out of the Copenhagen workshop and includes contributions from the wider research community.

Virtual Infinity Seminars

The Virtual Infinity Seminar series began in October 2023 and continues to bring researchers together online. The seminar archive and schedule provide links to individual talks, slides, and video recordings, including seminars from 2024, 2025, and 2026.

Newsletter

Our newsletter, Hyperbolic Times, shares research developments, publications, and seminar announcements.

Shared resources

The network’s resource page links to tutorials and working wave-equation solvers. Our online book Hyperboloidal Compactification in NGSolve and its public repository provide finite element examples. The education page collects these materials alongside browser-based notebooks for wave propagation and black-hole perturbations.
