High energy physics involves the study of the fundamental building blocks of nature at the shortest distances. These are the fundamental particles that are described by quantum fields such as the Higgs field found at CERN's Large Hadron Collider (LHC). Our group studies theories beyond the Standard Model of particle physics both from theoretical and phenomenological perspectives.

The II Workshop on Fundamental Fields and Compact Objects, integrated in the NewFunFiCO network, will be held in person at the Institute of Physical Sciences, UNAM-Morelos, Mexico, 17–19 November 2026. More info here.
The XIX edition of the Black Holes Workshop will take place at the University of Minho, on 17-18 December 2026. More info here.
"The extreme gravity of astrophysical compact objects", a workshop integrated in the NewFunFiCO network took place in Frankfurt in June 2026. A great atmosphere, a variety of interesting science and lively discussions made a great event. The photo was taken in the rooftop of the venue, the historical building where the Stern-Gerlach experiment was conducted in 1922.
In April 2026 we received the visits of Maryem Jemri (Rabat) and Justin Feng (Prague). Thank you for your seminars and the great scientific interactions!
