Worked on improving physics accuracy in detector simulations by correcting aerogel refractive index values in both the eic/EICrecon and eic/epic repositories. Addressed two critical bugs by updating the refractive index from 1.019 to 1.026, which enhanced the consistency between simulation and experimental data, particularly for reconstructed Cherenkov angles. Ensured backward compatibility by implementing non-breaking changes and updating default configuration values in C++. Communicated updates and provided migration guidance to collaborators, supporting reproducible physics analyses. Demonstrated expertise in detector physics, physics simulation configuration, and collaborative development workflows using C++ and Git-based version control across multiple codebases.
