Jaime Mendizábal Roche

Jaime Mendizábal Roche (born Madrid, 1994) is a Spanish mathematician. He represented Spain at the International Mathematical Olympiad in 2011 (Bronze Medal) and 2012 (Honourable Mention). He read a Double Degree in Computer Engineering and Mathematics at the Universidad Complutense de Madrid (2012-2017, Extraordinary Prize), spent an Erasmus year at TU München working as a research assistant in logic and verification, and completed an MASt in Pure Mathematics at the University of Cambridge (2017-2018) on a Fundación 'la Caixa' fellowship. From 2018 he pursued a PhD in mathematics at University College London in the LSGNT doctoral training centre on monopoles and gauge theory, passing his viva on 5 June 2024.

• Quant employment verification: UNRESOLVED. No actual past/present role or internship at a quantitative finance employer (investment bank, asset manager, energy/crypto trading firm, market-maker, hedge fund, or systematic/algorithmic trading firm) was found for Jaime Mendizábal Roche; the only employment lead supplied (Natixis Corporate & Investment Banking, 'Analista de sistema', from 2023-04) resolves to a different namesake - an IT systems analyst whose career (Playtech 2020-2023, Drago Solutions 2013-2019) cannot be the mathematician's - and the Natixis title is an IT/systems role, not a quantitative-finance role, even for that namesake. His documented record is academic: UCM double degree, Cambridge MASt, UCL/LSGNT PhD in gauge theory (viva 2024). Identity of the academic subject is supported by primary sources (La Caixa fellowship, LSGNT CDT, UCL news); no employment at a quant firm is supported by any source.Sep 2026
• Distinct-person warning: a different Jaime Mendizábal (LinkedIn /in/jaime-mendizabal-7a94881a9) is an IT/systems analyst ('Analista de sistema') at Natixis Corporate & Investment Banking with a prior systems-admin career at Playtech (2020-2023) and Drago Solutions (2013-2019) - a career path incompatible with the Olympiad mathematician's academic timeline, so the caller-supplied Natixis role lead does NOT belong to this subject.Jan 2026
• Identity: the Spanish IMO contestant (2011, 2012) is Jaime Mendizábal Roche, born in Madrid in 1994; the La Caixa fellowship biography ties the IMO Bronze Medal to the same name, birth year and city, and lists the UCM degree that follows the Olympiad years.Jan 2017
• No quantitative-finance employer, internship or trading role surfaced for Jaime Mendizábal Roche across searches of his name with quant firms (Jane Street, Optiver, Susquehanna, Citadel), 'trading', 'hedge fund', 'quant' and 'investment banking'; his documented professional record is academic mathematics.Sep 2026
• PhD in mathematics (LSGNT CDT, University College London, from 2018) in differential geometry / gauge theory; passed his viva on 5 June 2024 with minor corrections, thesis 'On monopoles with arbitrary symmetry-breaking and their moduli spaces', supervised by Michael Singer.Jun 5, 2024
• Authored 'Hyper-Kähler moduli spaces of monopoles with arbitrary symmetry breaking' (arXiv 2306.03069, 2023), published 2024 in Annals of Global Analysis and Geometry (Springer).Jan 2024
• Hold a 2017-2018 MASt in Pure Mathematics at the University of Cambridge (essay on the Hodge decomposition theorem), funded by a Fundación 'la Caixa' postgraduate fellowship for study in the United Kingdom.Sep 2017
• Completed a Double Degree in Computer Engineering and Mathematics at Universidad Complutense de Madrid (2012-2017), finishing with an Extraordinary Prize (Premio Extraordinario).Jul 2017
• Spent a year at Technische Universität München on Erasmus and worked for a few months as a research assistant in the chair of logic and verification, formalising number-theory results in the Isabelle proof assistant - an academic assistantship, not a competition.Jan 2015
• Represented Spain at the International Mathematical Olympiad twice: 2011 Bronze Medal (17 pts, rank 222) and 2012 Honourable Mention (10 pts, rank 350).Jul 2012
• Still active in the geometry community in 2024 after the PhD: spoke on Hyper-Kähler moduli spaces of monopoles at the solitonsatwork seminar (Aug 2024) and gave a 2024-25 Imperial Junior Geometry Seminar talk, and his arXiv 2306.03069 preprint has been cited by later monopole work.Aug 20, 2024
• Named in the Spanish BOE (2010) as a student of I.E.S. Ramiro de Maeztu (Madrid) selected for Spain at the International Mathematical Olympiad - a primary-source anchor for his secondary school and Olympiad identity.Jul 2010
