Rockstar🎓
Top SchoolDavid Carlisle is a Principal Technical Consultant and Staff Engineer with 28 years of experience blending deep mathematical training (PhD, The University of Manchester) with longtime engineering roles at Numerical Algorithms Group and sustained involvement in the LaTeX Project since 1989. He brings rare domain expertise in technical standards and markup for mathematics as an Invited Expert and Co-Chair of the W3C Math Working Group and editor of MathML-related recommendations. David’s open-source contributions include substantive kernel-level maintenance to the widely used LaTeX2e system, refactoring table and package internals that benefit millions of scientific documents. He excels at taking complex, formal specifications and turning them into robust, maintainable software and tooling for researchers and engineers. Based in the Greater Oxford area, he pairs academic rigor with decades of consultancy experience, often operating at the intersection of numerical algorithms, document preparation, and standards. A less obvious strength is his sustained ability to refactor legacy codebases—improving internal structure without disrupting vast existing user communities.
