Anastasios Stylianou

Anastasios Stylianou (also 'Tasos') is a mathematician by training and a quantitative strategist in London. He represented Cyprus at the International Mathematical Olympiad in 2011, 2012 and 2013, earning an Honourable Mention in 2012, then read Mathematics at the University of St Andrews (MMath (Hons), 2014-2018), graduating with an overall average of 96% and several prizes, before completing a PhD in Mathematics at the University of Warwick (2018-2022) under Professor Richard Sharp, on asymptotic counting problems for periodic orbits and equidistribution for hyperbolic dynamical systems. While a PhD student he worked as an online educator for Numerade and as a Graduate Teaching Assistant/Supervisor at Warwick. From 2022 he has worked at Rothesay (Rothesay Life plc), the UK pensions-insurance specialist, in the Quantitative Strategist function.

• Quant employment verification: CONFIRMED. Anastasios Stylianou ('Tasos') has an actual, currently-held quantitative-finance role: Quantitative Strategist at Rothesay (rothesay.com), the London-based UK pensions-insurance specialist (formerly Rothesay Life plc, a bulk-annuity/risk-transfer insurer, St James's Place group). The role is listed as current from 2022 (LinkedIn), and Rothesay's own careers pages advertise a distinct 'Quantitative Strategist' function/graduate and internship programme with quant-strategist and quant-developer job specs, so the employer genuinely operates a quantitative function rather than merely carrying 'quant' in its name. Identity is supported: the profile's education (MMath St Andrews, PhD Warwick) matches the Warwick CV and thesis records of the same name. Classification: quant employer = insurance/pensions asset manager with an in-house quant strategist function (not a bank, market-maker or hedge fund). Index-only caveat: the specific 2022 start/end dates for the Rothesay role come from the LinkedIn people-index, not independently confirmed on a primary page.
• Earned an Honourable Mention for Cyprus at the 53rd IMO (Mar del Plata, Argentina, 2012), scoring 12 points (302th of 547), with individual problem scores 7/0/0/2/3/0; he is the only 'Anastasios Stylianou' on the Cyprus team that year.Jul 2012
• Did a funded PhD in Mathematics and Statistics at the University of Warwick (Oct 2018 - 2022) supervised by Professor Richard Sharp, on asymptotic counting problems for periodic orbits and equidistribution for hyperbolic dynamical systems; supported by departmental funding.2022
• Represented Cyprus at the IMO in three consecutive years - 2011 (score 466), 2012 and 2013 - i.e. his 2013 appearance was as a fourth/upper-secondary pupil before starting university in September 2014.Jul 2011
• Completed an MMath (Hons) in Mathematics at the University of St Andrews (Sept 2014 - June 2018) with an overall average of 96% (19.2/20), writing a thesis 'Extremely non-normal numbers in dynamical systems' under Professor Lars Olsen.Jun 2018
• Rothesay's Quantitative Strategist roles are separately advertised with their own graduate and 2026 internship programmes plus quant-strategist and quant-developer job specs, confirming the function is a real quantitative team rather than a generic actuarial label.
• Distinguishing primary vs index evidence: the role history, current title and 2022 start dates are LinkedIn-index claims (Work history: 'Quantitative Strategist at Rothesay'; Educator at Numerade 2020-2021; GTA/Supervisor Warwick 2018-2022); the education, awards, publications and IMO results are independently corroborated by primary pages (Warwick CV PDFs, WRAP thesis, arXiv, imo-official.org).
• Gave preparation lectures on elementary number theory to the Cyprus IMO team at an IMO training camp in June 2016 while an undergraduate - a teaching/volunteer role, not a paid quant position.Jun 2016
• Rothesay is a UK bulk-annuity/pensions-insurance specialist (risk transfer, buy-in/buy-out), part of the St James's Place group; its quant work sits inside an insurer/asset-manager context rather than a hedge fund or prop-trading firm.
• Talks his final paper at 'UK Ergodic Theory and Dynamical Systems' (ComPlane: the next generation) in October 2020, evidencing an active pure-maths research profile through the PhD.Oct 2020
• First-author/co-authored 'A typical number is extremely non-normal' (arXiv 2006.02202, math.NT, June 2020), published in Uniform Distribution Theory.Jun 2020
• Publication 'On the Hausdorff and Packing measures of typical compact metric spaces', Aequationes Mathematicae 92, 709-735 (2018), co-authored with S. Jurina, N. Macgregor, A. Mitchell and L. Olsen.2018
