Panagiotis Lolas

Panagiotis Lolas is a mathematician who represented Greece at the International Mathematical Olympiad in 2011 (bronze), 2012 (gold) and 2013 (silver). He studied mathematics at MIT (BS, 2017) and completed a PhD in Mathematics at Stanford University in 2022, with advisors Lexing Ying (Mathematics) and Iain Johnstone (Statistics); his dissertation is titled 'Eigenvalue Shrinkage Methods in High-Dimensional Estimation'. His Stanford department profile lists his first position after graduating as Quantitative Researcher at Vatic Investments, and his LinkedIn lists summer quantitative roles at Two Sigma and The D. E. Shaw Group.

Notes5

• Quant employment verification: CONFIRMED. Stanford University's own Mathematics department profile (an institutional departmental record, not an index or aggregator) states his first position after graduating in 2022 was Quantitative Researcher at Vatic Investments, which is a supported identity: the same LinkedIn handle (panagiotis-lolas-366366113) carries the Stanford PhD and the Two Sigma/D. E. Shaw quant roles, and the profile matches the Greek IMO medalist. Vatic Labs (vaticlabs.ai) is a quantitative/automated-trading firm ('Where automated trading evolves'), so it operates in quantitative finance and the role is a genuine quant research role. The Two Sigma (Quantitative Researcher intern, Jun-Aug 2021) and D. E. Shaw Group (Quantitative Research Analyst intern, Jun-Sep 2020) entries come only from the LinkedIn enrichment index and aggregator copies (RocketReach/AeroLeads), i.e. index-only, not independent primary-source confirmation; both are 3-month summer windows consistent with internships.
• Stanford department page lists his first position after graduating as Quantitative Researcher at Vatic Investments.
• International Mathematical Olympiad record: bronze (2011, 253rd, 16 pts), gold (2012, 33rd, 28 pts) and silver (2013, 61st, 28 pts), all representing Greece.
• Stanford Mathematics PhD 2022; dissertation 'Eigenvalue Shrinkage Methods in High-Dimensional Estimation'; advisors Lexing Ying (Mathematics) and Iain Johnstone (Statistics).
• Career pattern across the two indexes (Stanford department record plus LinkedIn enrichment): summer quant internships at The D. E. Shaw Group (2020) and Two Sigma (2021) during the PhD, then a full Quantitative Researcher role at Vatic Investments after the 2022 PhD - a sequence of quant roles at three separate firms, though only the Vatic post is backed by a non-index source.
• Vatic Labs is a quantitative automated-trading firm; its own site describes it as 'Where automated trading evolves', supporting its classification as a quantitative finance / systematic trading employer rather than a generic tech firm.
• Co-authored arXiv:2010.15817 'sigma-Ridge: group regularized ridge regression via empirical Bayes noise level cross-validation' with Nikolaos Ignatiadis (submitted Oct 2020).
• Listed as PhD alumnus in Stanford Mathematics (graduation year 2022) with an office in Building 380 and faculty advisors Lexing Ying (Mathematics) and Iain Johnstone (Statistics); MIT is his undergraduate institution.
• Undergraduate research at MIT (UROP+, summer 2016): 'Asymptotics at the Edge of Multilevel Discrete beta-ensembles', mentor Evgeni Dimitrov, project suggested by Prof. Vadim Gorin.
