Aled Walker

I am a quantitative researcher in the Xantium Group at Tudor Capital Europe. Until August 2024 I was a pure mathematician academic, being a Fellow at Trinity College Cambridge and a permanent Lecturer/Assistant Professor at King's College London. In 2010 I represented the UK at the International Mathematical Olympiad.

• Quant employment verification: CONFIRMED. Evidence: his LinkedIn profile states a current Quantitative Researcher role at the Xantium Group - Tudor Investment Corporation from September 2024, and his profile summary states he joined the 'Xantium Group at Tudor Capital Europe' after leaving academia in August 2024. This role evidence is derived from the LinkedIn profile via the people index (self-published profile), NOT an independent primary source; the firm's team page does not list him. Identity is supported and consistent: the profile's headline references representing the UK at the 2010 IMO and describes the same Cambridge/Oxford pure-maths academic career (Trinity College Cambridge, King's College London) as the IMO 2010 UK contestant. Employer classification: Xantium Group is a quantitative/systematic trading investment manager (xantium.com) spun out of Tudor Investment Corporation - an established hedge-fund firm - so this is a genuine quantitative finance employer. No quantitative-finance role was found predating 2024; all prior roles are academic. Residual uncertainty is limited to the absence of independent non-index confirmation of the role.
• Complete career timeline (all pre-2024 roles academic/mathematical, sourced to his LinkedIn profile via the index): Junior Research Fellow, Trinity College Cambridge 2018-2024; Postdoctoral Research Fellow, CRM Montreal 2019-2020; Lecturer, McGill University 2019; Junior Fellow, Institut Mittag-Leffler 2021; Stipendiary Lecturer (Career Development) in Pure Mathematics, Pembroke College Oxford 2017-2018; Programme Associate, MSRI Berkeley 2017; summer-school tutor, Cambridge Immerse 2017; freelance audio producer, National Geographic. No trading/internship roles appear for the pre-2024 period.
• IMO 2010 UK team: Luke Betts, Nathan Brown, Andrew Carlotti, Richard Freeland, Sergei Patiakin and Aled Walker; team leader Geoff Smith. Aled Walker authored the team's student report (dated 2010-09-09).
• INDEX-ONLY (LinkedIn-derived): summary states he was a pure-maths academic until August 2024 (Fellow at Trinity College Cambridge; permanent Lecturer/Assistant Professor at King's College London) and is now a quantitative researcher in the Xantium Group at Tudor Capital Europe.
• Xantium Group is a systematic/quantitative investment firm and team structure ('how we work') hosted at xantium.com; founded as a spin-out from Tudor Investment Corporation (an established macro hedge fund).
