As a researcher in experimental particle physics I study the smallest building blocks of matter and the forces through which they interact. I'm interested in solving the shortcomings of the Standard Model of particle physics, and in particular searches for particles that can make up the Dark Matter that dominates our universe.

My main research activities are within the ATLAS experiment at CERN's Large Hadron Collider (LHC). Recent responsibilities within the experiment include:

• Luminosity measurements (2022-2023)
• Searches for physics beyond the Standard Model withlong-lived particles (2016-2023).
• Coordination of preparations for the physics program at theHL-LHC(2019-2021)
• Coordination roles in the High-Granularity Timing Detector project, which will equip ATLAS with30-50 ps timing resolution at the HL-LHC (2018-2020)
• Working group fordark matter (2018-2019)

In 2019 I was appointed a member of the Young Academy of Sweden, and in 2023-2024 I am a member of its board. I was a member of the board for the Elementary Particle Physics and Astroparticle Physics section of the Swedish Physical Society 2018-2021, and in Stockholm I organize the working group for Beyond-SM physics and am a member of the Steering Group of the Oskar Klein Centre.

I'm currently based in Stockholm, but between 2006-2017 I spent around 85% of my time at CERN. During 2014-2017 I was employed by Berkeley Lab and before that I was a Research Fellow at CERN. I defended my PhD thesis at Stockholm University in 2011.

My research is funded by the Swedish Research Council (Starting Grant 2018-2022, Project Grant 2023-2026).
