As the lead analyzer and analysis contact, Zirui has significantly improved the precision of Higgs interaction measurements, with results published in Nature in 2022. Additionally, he has established the most stringent upper limit on the Higgs invisible decay branching ratio on LHC to date and achieved the best sensitivity for the LHC dark matter benchmark model 2HDM+a

Zirui contributed to the calibration of the ATLAS Monitored Drift Tube (MDT) muon detector, playing a key role in detector operations and upgrade preparation. He now leads the Fudan University CMS group in the CMS HGCAL Upgrade, with responsibilities spanning module production, software development, and test-beam studies.

Since 2022, Zirui has served as the convener of the ATLAS experiment Common Dark Matter physics subgroup, coordinating dark matter searches within the ATLAS experiment. He has also worked in the LHC Dark Matter Working Group as the ATLAS experiment contact person, to establish the LHC dark matter benchmark model and plan for related physics analyses
