Mohammad Jahangoshahi

Mathematician and quantitative researcher; IMO 2008 silver medalist for Iran. PhD in Mathematics from the University of Chicago (2018, advisor Gregory F. Lawler), dissertation 'On Multiple SLE Measures'. Published on noisy group testing, Schramm-Loewner evolution, and randomized block numerical linear solvers. Research papers list his affiliation as Susquehanna International Group (SIG). A LinkedIn/index record identifies him as a Quantitative Researcher at SIG in Chicago; that specific current role is index-only and not independently confirmed, though the SIG affiliation itself is corroborated by peer-reviewed paper affiliations.

• Quant employment verification: CONFIRMED. Mohammad Jahangoshahi is a mathematician with a verified identity (UChicago PhD 2018; IMO 2008 Iran silver medalist) whose published numerical-linear-algebra papers state his affiliation as Susquehanna International Group, Bala Cynwyd, Pennsylvania, established by the author affiliation lines on his arXiv papers (arXiv:2104.04816, arXiv:2204.01653) and the SIAM Journal on Matrix Analysis and Applications paper 'An Implicit Representation and Iterative Solution of Randomly Sketched Linear Systems'. SIG is a global market-making/proprietary trading firm, i.e. a genuine quantitative-finance employer. His specific job title 'Quantitative Researcher' rests on the LinkedIn/index enrichment record alone (index-only) and is not independently confirmed, but the quant-finance employment itself is confirmed by author-affiliation evidence.Apr 10, 2021
