Steinar Stapnes

Steinar Stapnes is a Professor at the Department of Physics, University of Oslo. His research focuses on High Energy Physics, particularly in particle detector development, collider physics, and experimental studies using the ATLAS detector at CERN. He contributes to the CompactLight Design Study and has expertise in radiation dosimetry for advanced radiotherapy applications.

Key research areas include top quark physics, Higgs boson decay mechanisms, and searches for new particles such as vector-like quarks and supersymmetric particles. His work leverages large-scale LHC collision data to advance understanding of fundamental interactions and detector performance. He is involved in the CERN Technology Project 2016-20 and collaborates on projects like CLIC linear collider studies.

Prominent contributions include studies on jet calibration, electron identification, and polarization measurements in ATLAS experiments. His recent publications address topics like FLASH radiotherapy dosimetry and electroweak boson interactions, reflecting a blend of applied and theoretical research in high-energy environments.
