David Vasak

David Vasak is a quantitative developer/researcher working at Quadrature, a London-based quantitative hedge fund, since September 2022. He represented Australia at the 2010 International Mathematical Olympiad (Astana), earning an Honourable Mention, after attending Sydney Grammar School. He studied Mathematics at the University of Cambridge (BA and MMath), where he also gave talks on the Birch and Swinnerton-Dyer conjecture. His career has been entirely in quantitative trading and market making: Quantitative Researcher at Citadel Securities (2017-2022), Software Developer at IMC (2015-2017), and a summer internship at IMC (2014). All three employers operate in quantitative finance.

• Quant employment verification -- CONFIRMED. Identity is supported (LinkedIn enrichment plus independent sources tie David Vasak, the IMO 2010 Australian team member, to University of Cambridge MMath and to Quadrature). Three quant-finance employers are all verified as genuine: Quadrature (Quadrature Capital) is a British quantitative hedge fund trading automated systems (Wikipedia classifies it 'UK-based quantitative finance hedge fund'; quadrature.ai 'automated trading systems'); Citadel Securities is a leading electronic market maker; IMC is a proprietary trading firm and market maker (Wikipedia 'proprietary trading firm and market maker, Amsterdam'). Roles are actual employment/internships, not student programs: Quantitative Researcher at Citadel Securities (2017-04 to 2022-08), Software Developer at IMC (2015-08 to 2017-03), Summer Intern at IMC (2014-07 to 2014-09), current Quant/Dev at Quadrature (from 2022-09). Note: the roles come from an index/LinkedIn-derived record (taiga lead) and were not independently confirmed on a primary employer page; treat the exact dates as provider-reported.Sep 17, 2026
• Current role is Quant/Dev at Quadrature (London quant hedge fund) from September 2022, per LinkedIn-derived enrichment; an aggregator (rocketreach) also lists 'Quant and Dev at Quadrature' with prior roles at Citadel Securities. This is the person a task lead flagged as the IMO 2010 Australian contestant.Sep 17, 2026
• Represented Australia at the 51st IMO (Astana, Kazakhstan, 2010) as AUS5, scoring 14 points (P1-6: 6,0,0,7,1,0), rank 266, Honourable Mention -- placing him mid-field on a team that included gold medallist Aaron Wan Yau Chong.Jul 1, 2010
• Educated at Sydney Grammar School (Higher School Certificate) and then University of Cambridge, where he earned a BA and an MMath in Mathematics -- the Cambridge MMath is a research-track master's, consistent with a strong pure-mathematics background before quant finance.Sep 17, 2026
• Gave a talk 'Local to global principles: the Birch and Swinnerton-Dyer conjecture explained' at the Trinity Mathematical Society Symposium 2015 (Cambridge) -- evidence of an advanced number-theory interest during his Cambridge years.Feb 22, 2015
• Cohort context: the 2010 Australian IMO team featured significant Sydney Grammar representation (Timothy Large, David Vasak), and Vasak later returned as a lecturer/helper for Australian mathematics olympiad training in 2014 ('Australian Scene 2014') -- a sustained link to the olympiad community.Jan 1, 2014
• Presented 'Everyone Hates Vector Calculus' at the Sydney University Mathematical Society (SUMS) as a Cambridge student -- early public teaching/speaking, after the IMO years.
