PROFILE
Daniel Limosnero
Daniel contributed to the IMSA-CMS/CMSAnalysis repository by developing and refining machine learning pipelines and data analysis tools for high energy physics research. He implemented Boosted Decision Tree models using C++ and ROOT, integrating them into the analysis workflow to improve signal discrimination and automate parameter extraction for Higgs studies. His work included retraining models, updating configuration management, and standardizing output formats for fit functions and channel parameters. Daniel also enhanced code maintainability through documentation and naming conventions, fixed data handling and logging bugs, and streamlined lepton-jet reconstruction logic, resulting in more reproducible analyses and robust, production-ready scientific software.
