Nikhef, the National Institute for Subatomic Physics in the Netherlands, is a leading research center in particle and astroparticle physics, collaborating with major Dutch universities and international experiments such as ATLAS at CERN. The Nikhef ATLAS group is deeply involved in detector construction, data acquisition, and advanced physics data analysis, with a strong focus on Higgs boson physics and searches for new physics. This postdoctoral position centers on the global optimization of diHiggs measurements, a key challenge for the LHC following the discovery of the Higgs boson. The successful candidate will develop and apply machine-learned surrogate models to optimize selection criteria for all two-Higgs decay signatures, aiming to surpass traditional local optimization methods. The project also explores future AI models capable of direct data analysis from low-level data. The postdoc will be embedded in the Nikhef diHiggs group, collaborating with PhD students and staff on Run-3 analyses of various Higgs decay channels. The position is part of a NWO-funded program, "The potential of the Higgs boson," which includes multiple PhD and postdoc positions focused on Higgs boson potential studies. The role offers excellent employment conditions, including a three-year contract, competitive salary, and additional benefits. Applicants should have a PhD in high-energy physics, strong data analysis and software skills, and experience with machine learning in particle physics. The application deadline is November 16, 2025, with interviews scheduled for December 8-10. For more details, candidates can refer to the Nikhef employment page or contact the listed supervisors.
