Rati Gelashvili

Distributed-systems researcher (PhD MIT; postdoc U. Toronto) working on the complexity of synchronization, population protocols and concurrent data structures. Industry: Neural Magic (Senior Algorithms Lead), Novi/Facebook (Research Scientist), and founding-team researcher at Aptos Labs. Early internships at Google, Facebook, Akamai, Microsoft Research, Dropbox and D.E. Shaw (quantitative hedge fund).

Notes8

• Quant employment verification: CONFIRMED. The subject's own personal site states he "interned at Google, Facebook, Akamai, Microsoft Reseach, Dropbox and D.E.Shaw" (https://www.cs.toronto.edu/~gelash/), and the LinkedIn profile index records a Quantitative Analyst role at The D. E. Shaw Group, Jun 2017-Sep 2017 (index-only claim, not primary-source confirmed). The D. E. Shaw Group is a quantitative/algorithmic hedge fund, so this is an actual quant-finance internship. Identity is supported: the same personal site is linked from the LinkedIn profile and the X bio, and it names the same PhD/MIT/ETH/olympiad background. No other quantitative-finance employer (bank, asset manager, energy/crypto trading firm, market maker) appears in any source read; only the D.E. Shaw internship qualifies.2017

• The LinkedIn index records the Aptos Labs 'Blockchain Researcher (Founding Team)' role as Jan 2022-Nov 2025, and his X bio describes Aptos as 'prev' - so Aptos is no longer current and the present employer is not established by any source read (as of 2026-09).Nov 2025
• D.E. Shaw internship is stated on his own personal site: "I did my undergrad at ETH Zurich and have interned at Google, Facebook, Akamai, Microsoft Reseach, Dropbox and D.E.Shaw." D.E. Shaw Group is a quantitative/algorithmic hedge fund - supports an actual quant-finance-adjacent internship.2018
• Won the ACM PODC 2018 Doctoral Dissertation Award for his dissertation 'On the Complexity of Synchronization' (MIT, advisor Nir Shavit) - a top distributed-computing honor.2018
• LinkedIn index lists Quantitative Analyst at The D. E. Shaw Group, Jun 2017-Sep 2017 (4 months), matching the caller lead; this is an index-derived claim and is independently corroborated only as to a D.E. Shaw internship by his personal site.Jun 2017
• X account @rgelash (verified, 38,003 followers) bio: 'Concurrency, prev blockchain research @aptoslabs, @novi. even prior eng team lead @neuralmagic, PhD @mit' - independently corroborates the career spine (MIT PhD, Neural Magic, Novi, Aptos) off the index.2025
• PhD in the Multicore Algorithms Group at MIT under Prof. Nir Shavit; afterwards Postdoctoral Fellow at University of Toronto with Prof. Faith Ellen - stated on his own site.
• Worked two years at NeuralMagic as Senior Algorithms Lead (and Engineering Team Lead), designing high-performance systems for running neural networks on CPUs.
• Continued as Research Scientist at Novi (Facebook), focusing on theoretical foundations of blockchain systems and practical scalability of Diem.
• Aptos Labs research page and Aptos Medium posts credit 'Alexander Spiegelman, Rati Gelashvili' - evidence of active, current-era (2024-2025) blockchain research at Aptos Labs.2025
• Authored/co-authored Block-STM (arXiv 2203.06871; appeared at PPoPP 2023), a parallel blockchain execution engine - blockchain systems research, not a quantitative-finance role.2023
