Kort presentation
The research of my theory group is focused on the strong interaction, one of the four known fundamental forces. We contribute to high-precision standard-model calculations with the aim to search for differences between nature and our theoretical description of it. In addition, we want to gain a better quantitative understanding how quarks form composite objects, the hadrons.
For more details see also the presentation of my research group.
You can find me at Ångström office 12136.
