Professor of elementary particle physics at Stockholm University

Deputy Head of Department.

Member of the ATLAS Collaboration

My research focus is search for beyond the standard model physics that may be connected to the Higgs mass hierarchy, Dark Matter, Baryogenesis and other outstanding questions. It is striking that these questions emerge in the same era and hard to believe that they would all have separate answers. This is the guiding principle behind the research topics and physics analyses I carry out, from new Higgs particles, to search for extra dimensions, dark matter particle production or supersymmetry. I am currently working on the analysis of ATLAS data Run-2 and Run-3 in search for news spin zero particles that would extend the Higgs sector and could answer several of these questions-

Together with other members of the Stockholm University ATLAS group I am deeply involved in the current construction of the electronics for the High Luminosity upgrade of the ATLAS Tile Calorimeter, in particular the radiation-hard DaughterBoard entirely developed in-house and for which our group has full production responsibility.

I was earlier project leader for the ATLAS Tile Calorimeter High Luminosity Upgrade, a project that gathers 24 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 new physics such as dark matter particles and beyond the standard model Higgs particles with ATLAS.

Other 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.
