• Quant employment verification: CONFIRMED. Identity is independently supported: Ruvim Khvoles represented Israel at IMO 1994 (bronze, rank 187, 19 pts) and earned a Bar-Ilan University PhD in 2006 (advisor Ziv Kizner) - the same Bar-Ilan affiliation and mathematics profile shown on the LinkedIn profile. That profile lists actual quantitative roles, not student programs: Quantitative Analyst at Barak Capital (2014-present), Senior Quantitative Analyst at Arakamba Trading (2010-2013), and Quantitative Researcher at Wexford Capital Israel (2006-2009). Employer classification against primary sources: Barak Capital is verified as a proprietary trading firm and official market maker providing liquidity with low-latency technology, and Wexford Capital LP is verified as an SEC-registered multi-strategy investment firm - both genuine quantitative-finance employers. Caveat retained: the specific role titles/dates rest on the LinkedIn profile (reproduced in the people index) and were not independently corroborated by a separate employment record; Arakamba Trading's business is not yet classified by a primary source.Sep 17, 2026
• Barak Capital (barakcapital.com) is an Israeli investment group that began as a proprietary trading firm and today is an official market maker providing liquidity on exchanges worldwide using low-latency technology, alongside underwriting - establishing it as a genuine quantitative trading/market-making employer.Sep 17, 2026
• The title carries the Hebrew word 'לזכרם' ('in their memory'), which on Israeli LinkedIn profiles commonly denotes a memorialized/deceased account; his last_active field shows 2026-03-31, so the memorial marker should not be read as a confirmed date of death from this data alone.Mar 31, 2026
• Wexford Capital LP is an SEC-registered, value-oriented multi-strategy investment firm (founded 1994; West Palm Beach/Greenwich/Oklahoma City) run by founding partners Charles Davidson and Joseph Jacobs - confirming the 'Wexford Capital Israel' entity as an investment-firm employer.Sep 17, 2026
• Doctorate: PhD in Mathematics, Bar-Ilan University, 2006; dissertation 'Quasigeostrophic localized vortical solutions: numerical construction and analysis', advisor Ziv Kizner - an appointment consistent with the Bar-Ilan researcher/lecturer roles listed on his LinkedIn.Jan 1, 2006
• Represented Israel at the 35th International Mathematical Olympiad (1994), scoring 19 points (6/7/3/1/1/1) for a bronze medal at rank 187 (51.7 percentile).Jul 1, 1994
• The LinkedIn profile headline reads 'Quantitative Analyst, Mathematician', with Bar-Ilan University as the listed association, tying the academic identity (Bar-Ilan PhD) to the quantitative-finance career in one profile.Mar 31, 2026
• Career timeline listed on the profile is internally consistent with the primary sources: Bar-Ilan research/TA (2001-2006) spans the PhD period (awarded 2006), then Wexford Capital Israel (2006-2009), a Bar-Ilan postdoc/lecturer return (2009-2012), Arakamba Trading (2010-2013), and Barak Capital (2014-present).Mar 31, 2026
• Arakamba Trading (Israel) precedes and overlaps the Barak Capital stint in the listed timeline (2010-2013); its actual line of business could not be classified from a primary source in this pass despite searches, so its quantitative-finance status is left unverified.Jan 1, 2010
• Listed skills centre on quantitative finance and applied mathematics - Matlab, numerical analysis, optimization, PDEs, time series analysis, statistical modeling, volatility, derivatives, option pricing, exotic derivatives, quantitative risk analysis, automated trading - consistent with a research/analyst (not front-office trading) profile.Mar 31, 2026
