I conduct research in particle physics within the ATLAS experimentet at CERN's Large Hadron Collider (LHC). My focus is on searching for extensions of the Standard Model that can explain the dark matter in the universe, the imbalance between matter and antimatter and the fine-tuning problem of the Higgs boson mass.

My present focus is primarily on searching for pair-production of Higgs bosons, in order to measure how strongly the Higgs boson interacts with itself. This parameter affects the shape of the Higgs potential, which in turn determines how the Higgs field affects the early evolution of the universe. If the Higgs potential has a shape that deviates somewhat from the shape predicted by the Standard Model, the electroweak phase transition that happened throughout the universe approximately a pico-second after the Big Bang could have been a turbulent first order phase transition in which the present imbalance between matter and antimatter could have developed.

I also search for the supersymmetric parter of the top quark. Between 2018 and 2023 I lead the SHIFT-project, a five year project funded by the Knut och Alice Wallenberg foundation where we develop and search for models with top quark partners with the aim of solving the Higgs fine-tuning problem.
