Szymon Majewski

Mathematician (University of Warsaw; PhD-track at the Institute of Mathematics, Polish Academy of Sciences) working in optimal transport, computational statistics and stochastic optimization. Co-author of 'Sliced-Wasserstein Flows' (arXiv 2018/2019) and 'Analysis of Langevin Monte Carlo via Convex Optimization' (JMLR 2019). Postdoctoral researcher at Ecole Polytechnique (2020-2022); since 2022 a Quantitative Researcher at G-Research, a London quantitative investment research firm, per LinkedIn-index records.

• Quant employment verification: UNRESOLVED. G-Research (gresearch.com) is a London-based quantitative investment research firm, so the employer is correctly classified as quantitative finance, not merely a name containing 'quant'. The role 'Quantitative Researcher, G-Research, from Jul 2022, no end date' appears in the LinkedIn-enrichment index and on theorg (an aggregator), both index/aggregator-derived rather than primary-source confirmation; no G-Research team/careers page, press item, conference bio, or other independent primary source confirming this role was located. Identity is supported (Polish IMO 2008 contestant id 17614; University of Warsaw; optimal-transport/MCMC publications; Scholar listing G-Research), so the person is supported but the specific employment role is index-only and remains explicitly uncertain. No past internship at a quant firm was found.
• Index-only claim (LinkedIn enrichment): current role is Quantitative Researcher at G-Research (gresearch.com, London), stated as starting 2022 with no end date; this is an index-derived field, not independent primary-source confirmation.
• IMO contestant id 17614: Szymon Majewski represented Poland at IMO 2008; the results page shows an individual score of 22 points and a silver medal.Jul 1, 2008
• Education from LinkedIn index: University of Warsaw (2007-2013) and Institute of Mathematics, Polish Academy of Sciences (2016-2020); the long Warsaw span starting in 2007 aligns with a student who sat IMO 2008, consistent with the identity being the same person.
• G-Research is a London-based quantitative investment research firm (financial services); the target appears among its Quantitative Research team on theorg (aggregator), consistent with a real quant-finance role rather than a name coincidence.
• Google Scholar profile (Quantitative Researcher, G-Research; verified gresearch.co.uk email) shows ~875 citations and research areas Computational Statistics, Optimal Transport, Stochastic Optimization - the academic identity and the G-Research employment cross-link on one page.
• Authored 'Sliced-Wasserstein Flows: Nonparametric Generative Modeling via Optimal Transport and Diffusions' (arXiv:1806.08141, v2 2019) with affiliation Institute of Mathematics, Polish Academy of Sciences - research publication in optimal transport / generative modeling.Jun 11, 2019
• Co-author on 'Analysis of Langevin Monte Carlo via Convex Optimization' (JMLR vol 20, 2019) with A. Durmus and B. Miasojedow, listed email [contact omitted] (Institute of Mathematics PAS), establishing the academic profile and institutional email.Jan 1, 2019
• Index-only claim (LinkedIn enrichment): prior role Postdoctoral Researcher at Ecole Polytechnique (Palaiseau, France), 2020-2022, before joining G-Research.
• Institute of Mathematics PAS doctoral-student listing carried an 'Announcement of Szymon Majewski's public defense', indicating a PhD trajectory at IMPAN leading into the Ecole Polytechnique postdoc.
• Namesake disambiguation: the prominent 'Szymon Majewski' journalist/TV presenter (b. 1967, Warsaw) and several engineers/dancers share the name; the IMO-2008 + University of Warsaw + optimal-transport-publications chain isolates the correct individual.
