About me

Professor of elementary particle physics at Stockholm University

Member of ATLAS Collaboration

Since March 2018 project leader for the ATLAS Tile Calorimeter High Luminosity Upgrade, a project that gathers 14 universities and institutes. The Tile Calorimeter of ATLAS is crucial for the whole ATLAS physics programme and plays an absolutely central role when looking for dark matter particles with ATLAS.

Past responsibilities: ATLAS run coordinator, chair and member of several ATLAS task forces, Editorial boards, convener of ATLAS Jet and Missing Energy working group, contact editor and analysis responsible for multiple data analysis papers since the start of ATLAS data taking.

My research focus is search for new beyond the standard model physics that may be connected to Dark Matter and the Higgs mass hierarchy problem. It is striking that these two questions emerged at the same time and hard to believe they have two separate answers. This is the guiding principle behind the research topics and physics analyses I chose to carry out, from search for supersymmetry to extra dimensions, dark matter particle production in lepton or monojet final states.

Higgs Particles, Baryogenesis and Gravitational Waves with ATLAS data

This project aims at developing a new class of experimental probes for new Higgs-like spin-0 particles with the ATLAS experiment at LHC, and to interpret the experimental results in complete models that predict primordial Gravitational Waves (GW).

Solving the HIggs Fine-Tuning Problem with Top Partners

In the Standard Model, the mass of the Higgs boson is greatly destabilised by quantum corrections, and free parameters of the model need to be extremely fine-tuned in order to arrive at the measured Higgs mass.
