• Quant employment verification: CONFIRMED. Actual roles at three quantitative-finance employers appear in his LinkedIn profile record: Quantitative Researcher at GSA Capital, Quantitative Researcher - Intern at WorldQuant, and Software Engineer - Intern (Core Development) at Jump Trading LLC. All three are genuine quant firms (see classification notes), and identity is supported by the matching LinkedIn profile, personal site and GitHub. Caveat: the role history is index-derived from the LinkedIn record and not independently republished by the employers.2021
• Patent record: named co-inventor on neural image/video compression patents assigned to InterDigital VC Holdings (from the Deep Render work) - US 12,731,298 granted 2026-09-08, US 12,026,924, application US 2025/0086843, and WO2022084702A1 (published 2021-10-25); co-inventors include Arsalan Zafar, Jan Xu, Christian Besenbruch, Bilal Abbasi, Chris Finlay, Christian Etmann.Sep 8, 2026
• Career trajectory from LinkedIn enrichment: Quantitative Researcher at GSA Capital (2021), then Research Engineer -> Senior Research Engineer -> Lead Research Engineer at Deep Render, then Senior Staff Scientist at InterDigital (which acquired Deep Render in 2025), now Research Engineering at ElevenLabs - a shift from quant trading into applied ML research.2026
• Current role: Research Engineering on voice agents at ElevenLabs, London (LinkedIn headline 'Research engineering, Voice agents @ ElevenLabs'); the people index independently lists title 'Research Engineering', company ElevenLabs.2026
• Employer classification: GSA Capital (gsacapital.com) describes itself as 'Sustained excellence in quant trading' running 'systematic trading strategies across all asset classes' - a genuine quantitative/systematic investment manager, so this lead is a real quant role distinct from the same-named gsacapital.mx real-estate developer.
• Olympiad record: IMO 2016 silver (26 pts, rank 68/602) and IMO 2015 bronze (18 pts, rank 140/577) for Bulgaria; also BMO 2015 silver (rank 15/117) and RMM 2015 honourable mention. He calls himself 'by heart a mathematician'.2016
• Employer classification: WorldQuant (worldquant.com) is 'a global quantitative asset management firm with over $7 billion in assets under management', founded 2007 by Igor Tulchinsky - a genuine quant asset manager.
• Employer classification: Jump Trading is a global proprietary trading firm trading every asset class, HQ Chicago, 13 offices in 8 countries - a genuine trading/market-making firm.
• Master's thesis '3D Object Reconstruction with RGB, Depth and Normals Data' at Imperial College London (2020-06-15), published on his blog.Jun 15, 2020
• Non-quant trajectory: Deep Render (deeprender.ai) is a London deep-tech startup building AI neural image/video compression; InterDigital is a wireless/patent-licensing R&D firm; ElevenLabs is an AI audio company. His post-2021 career is deep-tech ML research, not quantitative finance.
• Education: MEng Computer Science (Artificial Intelligence and Machine Learning) at Imperial College London; secondary at Sofia High School of Mathematics.
• Writes a personal blog (cherganski.com) on maths/ML; posts include a formal geometry proof (2022-04-01) and a probabilistic treatment of supervised learning with a Python notebook (2021-04-04).Apr 1, 2022
