PROFILE

David Mcdougall

Worked on the neuronsimulator/nrn repository to enhance build reliability, Python integration, and simulation fidelity over a three-month period. Delivered features such as environment variable configuration for the NMODL transpiler, enabling robust discovery of Python libraries and modules using CMake and Python, which improved cross-platform builds and onboarding. Integrated the Matexp solver and exposed key variables in NMODL VERBATIM sections to support accurate neuron model definitions and solver reliability. Improved installation workflows for NEURON Python components by refining CMake configuration and documentation, ensuring consistent Python packaging and easier setup. Demonstrated expertise in C++, CMake, Python, and technical documentation.

June 2026 – NeuronSimulator/nrn: Key focus on Python component installation and environment setup. Delivered enhanced CMake configuration for NEURON Python components, including NRN_INSTALL_PYTHON_PREFIX usability and a minimum CMake version of 3.20, plus clearer docs on Python component installation paths and PYTHONPATH requirements. No major bugs fixed this month; the changes improve installation reliability, cross-environment consistency, and developer onboarding for Python integration. Business value: faster user adoption of Python-enabled builds, reduced setup friction, and easier maintenance of the Python packaging flow. Technologies/skills demonstrated: CMake build improvements, Python packaging considerations, comprehensive documentation, and strong change traceability.

Month: 2026-02 — Focused on improving build reliability and integration between NMODL and the Neuron simulator in the nrn repository. Key feature delivered: NMODL Transpiler Environment Variable Configuration, enabling the transpiler to locate Python libraries and modules by configuring environment variables. This change reduces build failures and smooths cross-platform usage. Major bug fix: nrnivmodl-cmake integration fixes (#3711), specifically wiring environment variable discovery to locate libpython (.so/.dll) and the NMODL Python module. Impact: More robust builds, easier onboarding for new contributors, and fewer environment-related issues during installation and CI. Technologies/skills demonstrated: CMake tooling, Python/C API interop, environment variable handling, cross-platform build considerations. Business value: Accelerates setup, improves reliability in automated pipelines, and strengthens integration with the Neuron ecosystem.
