Summary
👤
Senior🎓
Top SchoolRam Sharma is a data-driven experimental particle physicist and Postdoctoral Research Associate at Purdue University with 11 years of experience extracting high-precision results from large-scale CMS data at CERN. He combines advanced statistical modeling, machine learning, and hands-on detector expertise to advance Higgs to di-muon measurements, high-pT muon identification, and Phase-2 trigger optimization. Ram has led large-scale analyses—from high-mass Higgs and aTGC measurements to the first-ever semi-leptonic VBS study in CMS—and supervised students while coordinating trigger and performance groups. His detector R&D spans GEM and HGCAL sensor characterization, radiation-aging studies, and calibration workflows, with practical improvements (e.g., 29% GEM efficiency gain) feeding design choices. He also contributes backend tools for Monte Carlo event processing, enhancing decay handling and LHE file workflows, reflecting a rare blend of analysis, software tooling, and hardware validation.

Contributions summary:Ram primarily worked on modifying and enhancing the "DECAY" program, a MadEvent tool for decaying unstable particles within the Standard Model. Their contributions included modifying existing files, specifically decay.f and decay_couplings.f, indicating a focus on refining decay processes and related physics calculations. Furthermore, the user implemented and modified LHE file splitter and merger scripts written in Python and C++, to handle different polarization states for particle decay, demonstrating an understanding of event file processing.
