• Quant employment verification: UNRESOLVED. The Citadel Securities 'Quantitative Researcher' role is index-only (LinkedIn enrichment / people_search agree) and unconfirmed by any primary or press source; the enrichment lists Citadel as current with start 2026 and there is no end date, so current employment must not be inferred. The one primary-source-funded employment segment is research/teaching at the University of Chicago (2017-2022). Citadel Securities does operate in quantitative finance (market-making/electronic trading). No evidence of any other quant employer was found.Sep 2026
