• Quant employment verification: CONFIRMED. Index-sourced LinkedIn data shows actual roles/internships at quantitative-finance employers: KCG Holdings (Quantitative Research Intern, 2015), The D. E. Shaw Group (Quantitative Research Intern 2016; Quantitative Researcher 2017-2021), and Citadel Securities (Quantitative Researcher, 2022-present), with a 2021-2022 non-compete period at D. E. Shaw. Identity is supported by the official IMO 2011 Singapore gold-medal record for Yue Ding plus matching education (Raffles Institution; Princeton BA Mathematics). Employer classification: KCG Holdings operated electronic market making/trading (acquired by Virtu Financial, 2017); The D. E. Shaw Group is a quantitative hedge fund; Citadel Securities is a market maker - all quantitative-finance firms. Caveat: the employment history rests on index-sourced profile data, not an independently read primary company source, and the current Citadel Securities role in particular is index-only.
• Won a gold medal for Singapore at IMO 2011 (52nd IMO, Amsterdam), scoring 28/42 (P1 7, P2 7, P3 0, P4 7, P5 7, P6 0), rank 39, 93.3%.Jul 2011
• Index-sourced LinkedIn profile lists a Quantitative Research Intern role at KCG Holdings in 2015 - KCG Holdings (kcg.com, Capital Markets) was an electronic market-making and trading firm formed from Knight Capital and Getco, acquired by Virtu Financial in 2017; an actual internship, not a student programme.
• Index-sourced profile lists Quantitative Research Intern at The D. E. Shaw Group (2016) then Quantitative Researcher at The D. E. Shaw Group (2017-2021), a quantitative hedge fund (deshaw.com) - actual research roles.
• Index-sourced profile then lists a Non-Compete Period at The D. E. Shaw Group (2021-2022) followed by Quantitative Researcher at Citadel Securities (2022-present); the non-compete listing is consistent with a move between competing firms, but the current Citadel Securities role rests on index data only and is not independently confirmed by a primary company source here.
• Employer classification: KCG Holdings (electronic market making/trading), The D. E. Shaw Group (quantitative hedge fund) and Citadel Securities (market maker) all operate in quantitative finance, so these roles satisfy the quantitative-finance employer criterion by company type.
• On the Singapore IMO 2011 team with a gold medal; attended Raffles Institution, Singapore, which runs the national olympiad training programme (education per index data).
• Employee-directory pages (RocketReach, ZoomInfo, SignalHire) list a 'Yue Ding' at Citadel Securities; these are auto-generated aggregators, not independent primary-source confirmation, so they only weakly corroborate the name-employer association.
