Summary
Anissa Dhouibi, Citi's global head of equities quantitative analysis, has officially joined Millennium Management following her resignation at the end of March 2026. Dhouibi announced the move publicly on LinkedIn on April 16, describing her six years at Citi as "wonderful" and expressing enthusiasm about joining the hedge fund. She collected her 2025 bonus before departing the bank, a typical timing for senior-level exits in financial services.
Dhouibi's departure represents a notable loss of quantitative talent for Citi's equities franchise. Prior to joining Citi in 2020, she held the same role as global head of equities quant analysis at JPMorgan and was understood to be well-regarded internally. Following her resignation, Citi briefly advertised her role through a London-based posting, seeking a "visionary" managing director with either a PhD or Masters degree and a minimum of 15 years' experience to lead the equities quantitative analysis team. The subsequent removal of this advertisement suggests Citi has either hired an external candidate or identified an internal successor, with unconfirmed reports pointing to EL Mostafa Ezzine, a London-based managing director and head of hybrids, as a potential replacement.
The specific nature of Dhouibi's role at Millennium remains undefined. It is unclear whether she will establish and lead a dedicated quantitative pod or integrate into the firm's existing centralized quantitative analyst team. Millennium Management, which manages $83.4 billion in assets as of January 2026, has demonstrated a pattern of recruiting quantitative talent from major financial institutions, including previous hires from Goldman Sachs and Citadel. The firm declined to provide immediate comment on Dhouibi's appointment, leaving details about her mandate and compensation structure undisclosed. Her move exemplifies the broader trend of senior quant talent migrating from traditional banking environments to multi-strategy hedge funds.
