Pachara Sawettamalya
Pachara Sawettamalya (nicknamed Akin) is a PhD student in the Theory Group at Princeton University, advised by Huacheng Yu, working on communication complexity, streaming/sketching, and sublinear algorithms. He earned a B.S. in Mathematics and Computer Science and an M.Eng. in Computer Science from MIT, where he was advised by Ronitt Rubinfeld, and is now looking for postdoctoral positions starting Fall 2027 or Spring 2028.
- Quant employment verification: UNRESOLVED. The only evidence for a quantitative-finance role is an index-derived LinkedIn record listing 'Quantitative Research Intern' at Jump Trading LLC (Chicago), dated 2020, on the subject's profile pachara-sawettamalya-6b6783192; no independent primary-source (company page, press release, or news) confirmation was found, so this remains an index-only claim and is recorded as uncertain. Jump Trading LLC is a proprietary high-frequency trading / market-making firm and therefore qualifies as a quantitative-finance employer if the role is confirmed.2020
- Rising fifth-year PhD student in the Theory Group at Princeton University, advised by Huacheng Yu; research spans communication complexity, streaming/sketching, and sublinear algorithms. Looking for postdoctoral positions in Fall 2027 or Spring 2028, which dates the PhD to roughly a 2022 start.
- Holds a B.S. in Mathematics and Computer Science and an M.Eng. in Computer Science from MIT, advised by Ronitt Rubinfeld.
- Research output includes co-authored papers on communication complexity and streaming sketches, e.g. 'Gap-Majority Lemmas in Communication Complexity' with Huacheng Yu (2026) and 'A (Very) Nearly Optimal Sketch for k-Edge Connectivity Certificates' (SOSA 2026).2026
- Thailand olympiad identity: reported as an IMO 2015 and 2016 contestant for Thailand; the imo-official contestant page returned a 'page does not exist' error, so the exact medal/score could not be confirmed from the primary IMO results source.2016
- Named an MIT EECS | Analog Devices Undergraduate Research and Innovation Scholar (SuperUROP) with a project on parallel and sublinear algorithms.
- Teaching assistant / instructor across several MIT courses (Computability and Complexity, Linear Algebra and Optimizations, Advanced Mathematics for Finance, Discrete Applied Mathematics), indicating a strong theoretical-CS teaching record.2021
- Machine Learning Intern at ATTA (atta-ai.com) in Bangkok in 2018, building UNet-based dermatological health algorithms; ATTA is a healthcare-AI company, not a quantitative-finance employer.2018
- Goes by the nickname 'Akin'; personal site lists 'Pachara but some people might know me as Akin'.
