A new geometry for Einstein's Theory of Relativity and Beyond

The Austrian Science Fund (FWF) has announced to fund the project A new geometry for Einstein's Theory of Relativity and Beyond in its new Emerging Fields excellency programme. The funding sum is an unprecedented 7 Million Euro. The project team consist of Michael Kunzinger , Raquel Perales , Chiara Rigoni , Clemens Sämann , and myself .
See the press releases of FWF , the University of Vienna and the Faculty of Mathematics.

Popuar talk

I gave the popular talk "Von Schwarzen Löchern und dem Urknall" (On black holes and the big bang) explaining some of my recent research at Vienna Planetarium.

Conference in Novi Sad

I gave an invited main lecture entiteled Impulsive gravitational waves (From particle motion to geometry) at the HASOP2023 conference in Novi Sad, Serbia.

Non-regular Spacetime Geometry at ESI

The ESI hosted our workshop Non-regular Spacetime Geometry , co-organised with Piotr Chrusciel, Melanie Graf, Ettore Minguzzi, and Mike Kunzinger.
