Research
I am a Professor in the Department of Physics and Astronomy of Uppsala University. My main research interests lie within Particle Physics and Particle Astrophysics. I am a member of the IceCube collaboration, an international group of researches operating the largest neutrino telescope in the world, and of the PTOLEMY collaboration, a fascinating and devishly difficult effort to detect the relic neutrinos that permeate the Universe from about one second after the big bang. The extremely low cross section of neutrinos with matter makes such measurement really challenging. But not impossible, and this is what PTOLEMY is trying to achieve.
Within IceCube, I am interested in the search for physics beyond the Standard Model, including dark matter, new particle searches and tests of fundamental physical laws with neutrinos. I am the co-lead of the Beyond the Standard Model working group of the IceCube collaboration. I was the Swedish contact and member of the management committee of the COST action "Quantum gravity phenomenology in the multi-messenger approach", where I was also the co-lead of the Neutrino Working Group.
