Adam P. Goucher

British mathematician and GPU/systems engineer at OpenAI. Cambridge Mathematics BA (2016) and PhD (2020); UK IMO 2011 bronze medallist. Career spans quantitative finance (Man AHL 2014-2017, J.P. Morgan 2018, Two Sigma 2019-2023), GPU programming (Spectral Compute 2019), and GPU algorithms at OpenAI (2023-). Long-running open-source work in cellular automata and a prominent mathematics blog.

Notes10

• Quant employment verification: CONFIRMED. Genuine quantitative-finance roles, not student programs: Quantitative Researcher at Two Sigma, London (2019-2023, 'execution modelling') - Two Sigma is a systematic/algorithmic quant hedge fund; and Quantitative Research Intern at Man AHL, London (2014-2017) - Man Group/AHL is a systematic managed-futures quant manager. Corroborating finance role: Associate at J.P. Morgan (2018) on LOXM, the bank's AI-powered execution algorithm (a bank quant/execution role, not a quant fund). Identity supported by four independent sources describing the same Cambridge mathematician: LinkedIn adam-p-goucher-82a049237, blog cp4space.hatsya.com, IMO 2011 UK team record, GitLab @apgoucher.
• Current role: Member of Technical Staff at OpenAI (since 2023), described as 'GPU algorithms' with headline 'Mathematician' - systems/GPU research, not a quant role, so the quant-finance period is past (2014-2023).
• PhD in Mathematics, University of Cambridge (2020); dissertation 'Topological and geometric inference of data', advisors John A D Aston and Jacob Andrew Rasmussen. The applied-topology/statistics subject matches his later GPU/ML work rather than pure combinatorics.Jan 1, 2020
• Represented the United Kingdom at IMO 2011 (Netherthorpe School), bronze medal, 21 points, rank 145 - the olympiad identity in the brief is verified to this person.Jul 1, 2011
• At Spectral Compute (2019) he wrote the GPU kernels behind what the company calls the world's fastest regular expression engine - an early GPU/performance role bridging his mathematics and his later GPU work at OpenAI.Jan 1, 2019
• Author of 'Differentiable Random Access Memory using Lattices' (arXiv 2107.03474, 2021, with Rajan Troll) - a differentiable memory module with O(1) access scaling to billions of entries, reflecting a lattice/geometry-driven approach to ML systems.Jul 7, 2021
• Maintains open-source Game-of-Life/cellular-automata tooling (apgluxe, lifelib) via GitLab @apgoucher, and co-established the omniperiodicity result in Conway's Game of Life - a long-running personal research programme.
• Writes the widely-read mathematics blog 'Complex Projective 4-Space' (cp4space.hatsya.com), his main public voice - combinatorics, cellular automata, number theory, puzzles.
• ORCID 0000-0002-2532-6950 lists the Cambridge PhD (DPMMS, from 2016) and links blog cp4space.hatsya.com, tying the scholarly identity to the same blog.Oct 1, 2016
• Wrote a student-perspective report on IMO 2011 for UKMT/British Mathematical Olympiad (referenced on the BMOS news page), showing sustained involvement in the UK olympiad scene beyond the contest itself.Aug 8, 2011
• X/Twitter handle @apgox ('Algorithmist, Cambridge') posts on mathematics and GPU/compiler topics (e.g. Triton linear-layouts), consistent with his OpenAI GPU-algorithms role.
• Oxford Online Maths Club credits 'Adam P Goucher' with a continued-fraction approximation to the length of the year, showing his recreational-number-theory results circulate in university outreach material.
