Evan O’Neil contributed to the ProteoWizard/pwiz repository by developing features and fixes that enhanced data processing, UI localization, and mass spectrometry workflows. He implemented Ardia file upload and PFAS data parsing, improving analytical capabilities for specialized compounds. His work included centralizing Win32 API P/Invoke calls in C# to streamline Windows interoperability and updating tutorial infrastructure for automated screenshot generation and localization readiness. Evan also addressed data integrity by validating chromatogram inputs, reducing runtime errors in Skyline. His technical approach emphasized maintainable code, robust data validation, and clear documentation, leveraging C#, XML, and Windows API expertise to support reliable scientific software.

October 2025: Delivered a critical data integrity fix for ProteoWizard/pwiz related to chromatogram handling. Added validation to ensure MeasuredResults contains at least one chromatogram and that SrmSettings cannot be in an invalid state when no chromatogram data exists, preventing errors in Skyline when exposed to a zero-length chromatogram list. This change reduces runtime failures and improves reliability of chromatogram processing across workflows.
