PROFILE
Davidcerny
Over 16 months, contributed to the revbayes/revbayes repository by building and refining core features for phylogenetic analysis, simulation, and statistical modeling. Leveraging C++ and Python, delivered robust algorithms for time-scaling, bootstrap estimation, and directed acyclic graph validation, while enhancing API safety and cross-platform compatibility. The work included implementing cycle detection, improving Monte Carlo diagnostics, and expanding integration tests to ensure reliability and reproducibility. Documentation and release workflows were modernized using YAML and CI/CD pipelines, streamlining onboarding and release cycles. These efforts improved scientific accuracy, developer productivity, and the maintainability of complex computational biology workflows in RevBayes.

Apr 1, 2026April 2026 (2026-04) — RevBayes Core delivered reliability improvements and established CI processes to accelerate quality and collaboration. Key changes include: 1) Fixed missing overrides to ensure correct polymorphic behavior in PhyloCTMCSiteHomogeneousDollo and StairwayPlotDistribution, addressing Clang compatibility and correctness; 2) Disabled the uniform partitioning distribution due to invalid calculations, with an explicit exception to protect users from misleading results; 3) Implemented continuous integration scaffolding with issue and PR templates and a build/test workflow, and merged developments to stabilize the codebase for release readiness. These changes reduce runtime risk, improve maintainability, and provide clearer developer guidance and faster feedback.
