• Quant employment verification: CONFIRMED. Karntikoon has a documented actual quantitative-finance role: Quantitative Researcher at Graviton Research Capital LLP (Singapore, from 2024), a high-frequency trading/market-making firm per its own site, and an earlier Quantitative Researcher role at Tech Square Trading (2018). Employer classification: Graviton Research Capital = high-frequency proprietary trading (quant finance, confirmed by its own description); Tech Square Trading = trading firm (index-only, caller lead, not independently verified as an operating quant firm); QuantCo = data-science/analytics firm (not trading). Identity is supported: the Princeton theory alumni page independently lists his current affiliation as Graviton Research Capital and the LinkedIn profile is linked from the IMO/USAMO/Princeton record context. Distinction: these are employment/internship positions, not student programs; his Uber and Google roles were research/software internships and QuantCo a data-science summer associate role. Uncertainty retained: the Graviton start month (2024-08) and the Tech Square Trading employment are not corroborated outside the LinkedIn/index lead, so those specifics remain index-only.Sep 17, 2026
