Angelos Pelecanos

Angelos Pelecanos is a PhD student in Computer Science at UC Berkeley, co-advised by Shafi Goldwasser and John Wright, working in theoretical computer science with a focus on cryptography and quantum computing. He earned an MEng (2022) and bachelors degrees in Computer Science and Mathematics (2021) from MIT, where he worked with Vinod Vaikuntanathan and Virginia Vassilevska Williams. Representing Cyprus, he won a Silver Medal at the International Olympiad in Informatics (IOI) 2017 and a Bronze Medal at the International Mathematical Olympiad (IMO) 2017. He held industry internships at Hudson River Trading (algorithm development, Summer 2021), Citadel (software engineering, Summer 2019), Tech Square Trading (quantitative trading, Winter 2019), and QuantCo (software engineering, Summer 2018).

• Quant employment verification: CONFIRMED. Actual internships are documented on his own site (apelecan.github.io, a primary self-authored source): Algorithm Developer Intern at Hudson River Trading (Summer 2021), Software Engineering Intern at Citadel (Summer 2019), Quantitative Trading Intern at Tech Square Trading (Winter 2019). Identity is supported: the site is the apex of a cross-linked identity loop (personal site -> GitHub apex; site carries his MIT degrees, UC Berkeley PhD affiliation, publications, and his LinkedIn handle), and his github.com/apelecan account and LinkedIn both point to the same person. Note: the LinkedIn/Crustdata index entries carrying the same roles are INDEX-ONLY evidence, not independent primary-source confirmation. Employer classification: HRT is a systematic/algorithmic trading firm; Citadel is a hedge fund/market maker; Tech Square Trading was a Boston-based quantitative market-neutral equities hedge fund (co-founded by Rohit Singh, per Preqin); QuantCo is a data-science/economics consultancy, NOT a quant trading firm. Caller's 'Citadel - Software Engineer (Jun-Aug 2019)' lead matches Summer 2019 SWE internship; the bare second 'Hudson River Trading' lead has no independent support.Sep 17, 2026
• Professional Experience from his own site: Algorithm Developer Intern at Hudson River Trading (Summer 2021); Software Engineering Intern at Citadel (Summer 2019); Quantitative Trading Intern at Tech Square Trading (Winter 2019); Software Engineering Intern at QuantCo (Summer 2018). All four are internships, not full-time roles.Jun 2021
• Research focus is theoretical computer science - cryptography and quantum computing; co-advised at UC Berkeley by Shafi Goldwasser and John Wright, with prior MIT MEng under Vinod Vaikuntanathan.Sep 2022
• Won the Silver Medal at the International Olympiad in Informatics (IOI) 2017 and the Bronze Medal at the International Mathematical Olympiad (IMO) 2017, competing for Cyprus; his Codeforces/IOI handle is 'AnPelec' (the caller lead's 'AnPelec' GitHub link is a handle confusion - his GitHub is 'apelecan').Aug 2017
• Publications include 'Online Shadow Tomography Matching the Classical Bounds' (with Sitan Chen, Ryan O'Donnell, John Wright) and 'The Keyl-Werner algorithm is not optimal for spectrum estimation' (with Jack Spilecki, Ewin Tang, John Wright).Jan 2026
• Elected to Phi Beta Kappa in 2021, the same year he graduated MIT with bachelors degrees in Computer Science and Mathematics.May 2021
• QuantCo is a data-science/engineering/economics consultancy headquartered in Boston, not a quantitative trading or investment firm - correctly distinguished from the trading roles.Sep 17, 2026
• Gave a theory talk at the Simons Institute (UC Berkeley) in March 2024 and a math/CS seminar at the University of Waterloo IQC, placing him in the quantum-computing/TCS seminar circuit.Mar 19, 2024
• All employer internships are consistent with the caller leads but the caller's date granularity is off: HRT was Summer 2021 (Algorithm Developer Intern), not necessarily a full-year term; the lead's second bare 'Hudson River Trading' entry has no independent support beyond the site.Jun 2021
• Tech Square Trading was a Boston quantitative market-neutral equities hedge fund (established 2012) whose co-founder/CEO was Rohit Singh; the firm fits the 'quantitative hedge fund' classification.2012
• Served in the Cyprus National Guard as a Second Lieutenant (2016-2017) between high school and MIT, per LinkedIn-index past roles.2016
