Contributed to the beast-dev/beast-mcmc repository by developing and refining features that enhance statistical analysis, model integration, and observability for phylogenetic workflows. Leveraged Java and object-oriented programming to implement new statistical calculations, integrate the ThreeDi amino acid substitution model, and expand metrics output for tree-state summarization. Addressed backend stability by correcting model type handling in tree likelihood computations, reducing analysis failures. Improved logging flexibility through dynamic trait naming and prefix support, facilitating more robust experiment tracking. Demonstrated strengths in algorithm design, code refactoring, and data analysis, consistently delivering targeted solutions that improve reliability and analytical depth across the codebase.

Jun 1, 2026June 2026 monthly summary for beast-dev/beast-mcmc. Focused on stabilizing tree likelihood computation by correcting the Tree Trait Provider Model Type usage. This targeted bug fix ensures DiscretizedSiteRateModel from the siteModel is not misinterpreted as GammaSiteRateModel, preventing syntax errors during the construction of ancestralTreeLikelihood and enabling reliable downstream analyses.

Sep 1, 2025September 2025: Beast MCMC delivered a targeted feature enhancement and resolved a critical integration bug, improving logging flexibility and observability for complex experiments. Key feature delivered: - DnDsLogger Prefix Support: Added a new prefix parameter to the DnDsLogger constructor and a getter method. The implementation dynamically builds trait names using the prefix, increasing logger flexibility and ensuring compatibility with CodonPartitionedRobustCounting when prefixes are used. Major bugs fixed: - Fixed DnDsLogger behavior when prefixes are used with CodonPartitionedRobustCounting (commit f82a89d16fc447b8e958451bc8aad76ec28eee63), ensuring correct trait naming and stable logging output in prefix-enabled configurations. Overall impact and accomplishments: - Enhanced observability and debuggability for configuration-rich experiments, reducing integration friction and time-to-insight. - Improved compatibility of beast-mcmc with advanced counting strategies, enabling more reliable performance assessments across configurations. Technologies/skills demonstrated: - C++ API design for extensible logging, dynamic trait naming, and parameterized constructors. - Debugging and patching in a live repository, with attention to regression safety and CI readiness. - Strong focus on business value through improved observability and workflow integration.

Dec 1, 2024December 2024 monthly summary for beast-dev/beast-mcmc: Focused on delivering a refined statistical calculation workflow that ties squared distance to input time, with support for time raised to the fourth power. The change introduces new constants, conditional logic, and helper methods, and integrates the new statistic into the existing statistics enumeration to improve usability across analytics pipelines. A subsequent refactor removed an unnecessary multiplication by four, ensuring raw time values drive correlations across Spearman, R-squared, and the correlation coefficient.
