Vytautas Gruslys

Mathematician (Cambridge PhD, combinatorics) and quantitative developer. Lithuanian olympiad medallist in both mathematics (IMO) and informatics (IOI). Roughly a decade at Cambridge across BA/MA/PhD and a Christ's College research fellowship, then a move into industry: software engineering at fintech Argyle and, since 2022, quantitative development at the systematic trading firm GSA Capital. Published combinatorics researcher (tilings, Boolean lattice, extremal graph theory).

• Quant employment verification: CONFIRMED. Index (LinkedIn enrichment) shows a current role as Quantitative Developer at GSA Capital, London, from 2022-09 — an actual professional role, not a student program. Identity is supported by converging records (IMO/IOI participation for Lithuania, Cambridge PhD thesis in the same name). Employer classification: GSA Capital (gsacapital.com) is a systematic/quantitative investment manager — confirmed by its own site ('quant trading', 'systematic trading strategies across all asset classes'), so the employer genuinely operates in quantitative finance. Caveat: the role itself rests on the LinkedIn index entry, not an independent primary-source page; no separate press/company confirmation of the role was found.Sep 2022
• PhD in Mathematics at the University of Cambridge; dissertation 'Tilings and other combinatorial results' (January 2018, Christ's College / DPMMS), proving Chalcraft's conjecture that any tile that tiles Z^d for some d and a conjecture of Lonc on partitioning the Boolean lattice.Jan 2018
• Prior industry role: Software Engineer at Argyle, 2020-2022. Argyle (argyle.com) is a payroll/income-verification data fintech, not a quantitative trading firm — so this role is adjacent fintech/engineering, not quant finance.2020
• Fellow in Pure Mathematics at Christ's College, Cambridge, 2015-2019 — a research fellowship overlapping the final years of the PhD, indicating an early academic career before the move to industry.2015
• IMO record: silver medal 2008 (rank 78, 85.6%), bronze medal 2007 (rank 171), honourable mention 2006 (rank 291), and a 2005 participation — all representing Lithuania.2008
• IOI record: bronze medal 2008 (88/283, 33.67%), plus participation in 2007 and 2006, representing Lithuania.2008
• Career transition: after the 2015-2019 research fellowship the timeline moves to software engineering (Argyle, 2020) and then quant development (GSA Capital, 2022) — a shift out of academic mathematics into applied software/finance.2022
• Published combinatorics researcher; work on tilings of Z^n and the Boolean lattice was discussed by Gil Kalai's blog and cited in the combinatorics literature (arXiv 1609.02520, 2008.05313).Apr 2018
• Education timeline at Cambridge: BA Mathematics 2008-2011, MA 2011-2012, PhD 2012-2018 (index).2018
• Represented Cambridge in the Oxford-Cambridge Varsity chess match 2012 and 2013 (Cambridge won the 131st match in 2013).Mar 2013
