PROFILE
Jack Davis
Worked on the IMSA-CMS/CMSAnalysis repository, delivering a suite of features and refactors to advance Higgs and LeptonJet analysis workflows in high energy physics. Applied C++ and the ROOT framework to implement event filtering, statistical modeling, and robust data analysis pipelines. Enhanced signal extraction by refining matching logic, introducing new veto filters, and improving histogram management for reproducible results. Systematically refactored fitting workflows and internal APIs to boost maintainability and efficiency, while addressing stability through targeted bug fixes. The work enabled more accurate background modeling, streamlined result categorization, and prepared the codebase for scalable, reliable physics analyses across multiple decay channels.
