PROFILE

M. Morgan Aster

Mary Morgan contributed to the broadinstitute/warp and workbench-libs repositories by developing and enhancing bioinformatics pipelines focused on genotype imputation and job observability. She implemented dynamic contig processing and robust version tracking in WDL workflows, improving data alignment and auditability. In workbench-libs, she standardized job status notifications, enabling automated, detailed reporting for Teaspoons pipelines. Her work included removing polling timeouts, expanding test coverage, and strengthening error handling, which increased reliability and operational transparency. Using Python, WDL, and Docker, Mary addressed both backend and workflow challenges, demonstrating depth in system design, workflow management, and the integration of cloud-based data processing solutions.

Feb 1, 2025

February 2025 monthly summary focusing on reliability improvements and expansion of genotype-imputation capabilities in broadinstitute/warp. Delivered a critical fix to Firecloud job status polling to remove the 15-minute timeout, added a completion log for better observability, and implemented a Beagle-based imputation pipeline for hg38 with supporting WDLs, Docker configurations, and tests to improve genotype accuracy and pipeline efficiency. These changes reduce downtime, improve observability, and enable more scalable analyses.

Dec 1, 2024

December 2024 monthly summary for broadinstitute/workbench-libs: Focused on enhancing user observability for Teaspoons job executions by introducing new notification classes. Added TeaspoonsJobSucceededNotification and TeaspoonsJobFailedNotification to standardize reporting with details like pipeline name, job ID, and resource usage. This enables timely user notifications and better operational visibility. No major bug fixes reported this month. Overall impact: improved reliability of Teaspoons pipeline notifications and reduced manual checks; supports operational automation. Technologies/skills demonstrated: API design for notification payloads, event-driven communication patterns, observability enhancements, code changes in a shared library, version control and issue-tracking integration (commit 3c3367e941a197007ec4b13ad3efc50e304eaeb6).
