PROFILE
Nicholas
Worked on the gem/oq-engine repository to expand seismic hazard modeling capabilities, focusing on the AvgSA correlation model and its integration with regional matrices for Europe and extended tectonic-region coverage. Migrated correlation coefficient storage from Python to HDF5, improving data access speed and scalability. Enhanced model reliability through improved initialization, error handling, and comprehensive documentation updates. Introduced Peak Ground Acceleration (PGA) support within AvgSA calculations and refined the testing framework to align with hazard validation standards. Leveraged Python, HDF5, and statistical modeling to deliver features that strengthen risk assessment accuracy, maintainability, and the foundation for automated, test-driven development.
