Aleksandar Lishkov

Aleksandar Lishkov is a quantitative researcher based in the Greater Chicago Area. He represented Bulgaria at the International Mathematical Olympiad from 2002 to 2005, winning gold in 2003 and 2005 and silver in 2004, and studied mathematics at Princeton University (class of 2009), where his senior thesis, advised by Rene Carmona, modeled temperature-difference contracts game-theoretically. Public aggregator records place him in a current quantitative research role in Chicago.

• Quant employment verification: CONFIRMED. The identity (LinkedIn /in/adl86, Greater Chicago Area, Princeton mathematics 2005-2009) is corroborated across independent records: an IMO results page gives his full name Aleksandar Dimitrov Lishkov, and Princeton's thesis repository lists a 2009 mathematics senior thesis by Lishkov. On employment, two aggregator records agree he holds a quantitative research role but disagree on the employer: a LinkedIn-index record shows 'Quantitative Research Specialist' at an unnamed 'Undisclosed Hedge Fund' since 2025 in Chicago, while a separate aggregator (wiza.co, updated 2025-11-01) names Citadel Securities with the title 'Quantitative Researcher'. Both are index/aggregator sources, NOT primary employer confirmation; the exact employer is unresolved, but a genuine quant-finance role (market-maker or hedge fund) is supported rather than a student program.Nov 1, 2025
• Represented Bulgaria at the International Mathematical Olympiad 2002-2005: gold medal 2005 (rank 35) and 2003 (rank 9), silver 2004 (rank 65). Caller also lists IMO 2001.
• Princeton University senior thesis in Mathematics (class of 2009): 'A Game Theoretic Approach to Trading Temperature Difference Contracts', advisor Rene Carmona, 63 pages; held at Princeton's Mudd Manuscript Library - a quantitative-finance topic predating his professional roles.2009
