• Quant employment verification: UNRESOLVED. The only support for his quant roles is his own LinkedIn/index profile; no independent primary source (employer page, filing, or third-party announcement) confirms any of the three roles. Xantium Group is a genuine quant trading firm; Evariste Technologies and Blaise AI are biotech/AI-drug-discovery companies.Sep 2026
• Full name is James Aaronson; represented the United Kingdom at IMO 2011 (St Paul's School, London) and IMO 2012 (St Paul's School), confirming the Olympiad identity in the brief against primary UKMT/IMO records.Jul 2011
• Index-only (LinkedIn, unverified): current role Quantitative Researcher at 'Xantium Group - Tudor Investment Corporation' (London) from 2026; prior Quantitative Developer at Blaise AI (2025-2026) and Quantitative Analyst at Evariste Technologies (2022-2026).

• DPhil (Mathematics) at Magdalen College, Oxford (2020), supervised by Prof. Ben Green FRS; listed on Green's own 'past students' page alongside Aled Walker, who is now also at Xantium Group - suggests the Xantium research desk recruits from this Oxford combinatorics group.2020
• Xantium Group is a real global multi-strategy investment firm that integrates quant research with human expertise and trades global markets, and posts Quantitative Researcher/Developer/Volatility Trader roles in London, NYC and Salt Lake City - consistent with operating in quantitative finance.2026
• 'Blaise AI' is an AI-first medicinal/small-molecule chemistry platform (LLM-orchestrated workspace for drug discovery), NOT a quantitative-finance firm; the adjacent title 'Quantitative Developer' there is a scientific-software role, not trading.2026
• A RocketReach profile lists a separate entity 'Evariste Quant Research'; and news coverage describes 'Evariste Technologies' as an AI drug-discovery startup partnering with the University of Southampton on oncology datasets - so Evariste Technologies is a biotech/AI-drug-discovery company, not a trading firm.2025
