Guilherme Zeus Dantas e Moura

Guilherme Zeus Dantas e Moura is a Brazilian mathematician and PhD student in the Department of Combinatorics & Optimization at the University of Waterloo, supervised by Olya Mandelshtam, where he also completed a Master of Mathematics (2025). He earned a Bachelor of Science in Mathematics and Linguistics at Haverford College (2024) and studied at Budapest Semesters in Mathematics (2022). As a high-school student representing Brazil he won a silver medal at IMO 2020 and a bronze at IMO 2019, and he is a two-time gold medalist at the Brazilian Mathematical Olympiad. His research is in algebraic and bijective combinatorics, especially permuted-basement nonsymmetric Macdonald polynomials, with publications in Algebraic Combinatorics, Fibonacci Quarterly, and conference proceedings.

• Quant employment verification: NOT CONFIRMED. The only quant-adjacent employment lead is a "Data Science Analyst" role at C CAPITAL (Rio de Janeiro, 2024), which appears ONLY in the LinkedIn index enrichment and is not corroborated by any independent primary source (his self-authored CV lists only academic and teaching roles). The employer C Capital (c.capital) is, per its own site, a private-markets platform investing in APAC private equity, private debt and control assets with >US$1.2B AUM - it is not a quantitative trading, market-making, hedge-fund or systematic/algorithmic trading firm, so the role would not qualify as quant employment even if confirmed. No other past/present role or internship at a bank, asset manager, energy or crypto trading firm was found. Student programs, competitions and olympiads do not establish employment. Classification: no confirmed quantitative-finance employer; sole lead is index-only and at a non-quant private-equity firm.
