• Quant employment verification: CONFIRMED. The LinkedIn profile (index-derived, not independently self-verified) lists a continuous quant-finance career: D. E. Shaw & Co. Quantitative Analyst 2006-2007; HBK Quantitative Analyst 2007-2008; Barclays Capital AVP 2008-2022; Rokos Capital Management / Rokos Family Office Quant Analyst 2015-2022; Balyasny Asset Management Senior Engineer, Macro Quant Research 2022-2024; Jane Street Software Engineer 2024-2026. Employer classification: D. E. Shaw, HBK, Rokos Capital Management and Balyasny verifiably operate in quantitative/systematic finance (hedge funds / multi-strategy asset managers) and Barclays Capital is a bank; Jane Street is a quantitative proprietary trading firm. All are actual roles, not student programs. Caveat: role dates and titles rest on the enrichment index and company_search classification; no independent primary-source confirmation of his specific roles was found.Sep 17, 2026

• Current LinkedIn headline lists a 'Temp' role at UCLES (Cambridge University Press & Assessment) and no listed quant employer; the most recent quant role shown is Software Engineer at Jane Street ending 2026-02. Do not read this as continuing employment at Jane Street - it is a past role in the current index.Sep 17, 2026

• His university education (Trinity College Cambridge; PhD Memphis under Bollobas) and his quant employers are separate phases: the PhD/Trinity/IAS research period precedes the 2006-onward finance career, so the finance roles are post-PhD professional employment rather than student credits.Jan 1, 2002
