Open source

Most of my open-source work is done within the Julia programming language ecosystem. I have been an active Julia user since 2016 and contribute to the SciML (Scientific Machine Learning) ecosystem, which provides the differential equations, optimisation, and machine learning infrastructure underlying much of my research. All of my code is on GitHub.

BarycentricInterpolation.jl

A simple implementation of Barycentric polynomials (interpolation and differentiation) for generic numeric types using Barycentric Lagrange Interpolation by Berrut and Trefethen (SIAM Review 46, pgs. 501-517) in Julia. Source code available from BarycentricInterpolation.jl on GitHub.

PDF2SVG

Note: Since this utility was written, the maintainers of Poppler have released pdftocairo, which works on the same principle and is better maintained. I recommend using pdftocairo instead. pdf2svg is still available but is no longer actively developed. A small program that converts a page of a PDF file into a Scalable Vector Graphics (SVG) file for editing in Inkscape. It wraps Poppler and Cairo and was quite popular when it was written, as there were few other utilities available at the time. ...

RTC

A real-time controller built around the BeagleBone Black single-board computer. It was developed to support control-based continuation experiments, where low-latency feedback control is needed to stabilise unstable periodic orbits in physical rigs. MATLAB and Python interfaces are available. The RTC provides functionality comparable to commercial real-time control hardware (e.g., dSPACE) at a fraction of the cost, making it accessible for university laboratory settings. See the GitHub page for the code. If you are interested in using or adapting it for your own experiments, please get in touch. ...
