Adrien Lemercier

Adrien Lemercier is a French mathematician-turned-technologist and quant researcher. He represented France at the International Mathematical Olympiad three times (2014, 2015, 2016; two silver, one bronze), studied applied mathematics and computer science at Ecole Polytechnique in the Ingenieur Polytechnicien program, and earned an MS in Computational and Mathematical Engineering (ICME) at Stanford. He completed numerical-methods research at Total before two quantitative research internships at Jump Trading (London 2021, Chicago 2022) and then a year as a full-time Quantitative Researcher at Jump Trading Group in New York (2023-2024). Since leaving Jump he has been founding a startup in San Francisco and runs the 'Ask a Quant' 1:1 mentorship service.

• Quant employment verification: CONFIRMED. Adrien Lemercier held actual quantitative roles at Jump Trading - Quantitative Research Intern (Jump Trading LLC, summer 2021 and summer 2022) and Quantitative Researcher (Jump Trading Group, Sep 2023 - Sep 2024). Identity is supported across LinkedIn, X (bio 'Prev quant @jumptrading, CS&math @Stanford, 3x IMO medalist'), his personal site, and GitHub. Jump Trading is a genuine proprietary/algorithmic trading firm, so the employer classifies as quant finance; these are employment, not a student program.
• Left Jump Trading around September 2024 and now describes himself as 'Building'. lemercier.com/about says he is building 'a company with immense ambition'. There is no current quant employer - do not infer current employment from the stale public LinkedIn headline 'Quantitative Researcher at Jump Trading'.
• 3x IMO medalist for France - 2014, 2015, 2016. Official IMO results: 2016 Silver (23 pts, rank 114), 2015 Silver (21 pts, rank 88), plus a 2014 medal.
• Building 'Diplo', an AI assistant project ('the AI layer between you and the outside world'), with a public GitHub repo and a Medium write-up dated March 2026 - a live builder signal for his current venture.
• Runs 'Ask a Quant' (askaquant.nanocorp.app), a paid 1:1 quant-finance mentorship service, explicitly branding himself 'Former quantitative researcher at Jump Trading' and 'currently building a startup in San Francisco'. Confirms the Jump quant role in his own public marketing and shows he monetizes that expertise as a mentor.
• During his 2022 Jump Trading internship he wrote the Pyth Network blog post 'Improving Lending Protocols with Liquidity Oracles' (Pyth is a crypto price-oracle network); his LinkedIn notes Pyth implemented the idea within ~6 months - evidence his quant research translated into a published protocol design.
• Career arc reads as a deliberate quantitative-research trajectory: applied-math degree at Polytechnique -> numerical-methods research at Total -> two Jump Trading quant internships -> 1 year as a full-time quant researcher -> departure to found a startup. The one-year stint is short for the industry, which suggests he left by choice to build rather than for performance reasons.
• Studied at Ecole Polytechnique (Ingenieur Polytechnicien program, applied math / math & CS) and Stanford ICME (MS Computational and Mathematical Engineering). Also attended EOGN (Ecole des officiers de la gendarmerie nationale) as 'Eleve officier' and served as an Officer at Gendarmerie Nationale - a French military/officer track distinct from his quant work.
• Research Intern in Numerical Methods at Total (energy major) - an energy-sector quantitative/technical internship, distinct from his Jump Trading roles and worth classifying separately in a quant-employment audit.
• Public X profile @adri_lemercier (verified, ~498 followers) with bio 'Building. Prev quant @jumptrading, CS&math @Stanford, 3x IMO medalist' - an independent corroboration of the whole identity and Jump history.
• States he is under NDA from his time at Jump Trading and cannot discuss strategies, signals, PnL or proprietary infrastructure - independent confirmation he was inside Jump's research function rather than an adjacent role.
• His 2021 Jump Trading internship (London) won the 'Best Research Internship in Applied Mathematics Award' at Ecole Polytechnique (1 of 100+ students) - an academic recognition attached to the industry internship.
