Ivan Losev

Ivan Losev (legal Belarusian spelling Ivan Loseu) is a Belarusian-American mathematician working in representation theory, symplectic geometry, algebraic geometry and combinatorial algebra. Born in Minsk in 1981, he represented Belarus at the International Mathematical Olympiad four years running (1996-1999), winning gold in 1999. He took an M.Sc. at Belarusian State University (2004), a PhD at Moscow State University in 2007 under E. B. Vinberg, then a CLE Moore instructorship at MIT before professorships at Northeastern University and, since 2019, Yale University.

Notes4

• Belarusian-American mathematician, full professor at Yale since July 2019; earlier full professor at Northeastern (2015-2018), associate professor there (2011-2015), and CLE Moore instructor at MIT (2008-2011).
• Born 18 Oct 1981 in Minsk; competed at the IMO from age 14 across four consecutive years, a prodigy trajectory that ran straight into Belarusian State University in 1999.Oct 18, 1981
• Publishes as 'Ivan Losev' but his passport/legal name is the Belarusian transliteration 'Ivan Loseu'; he prefers 'Losev' because non-speakers misspell 'Loseu'.
• IMO record: contested for Belarus 1996-1999, peaking at a gold medal and rank 6 (36 pts) in 1999; silver 1997 (31 pts), silver 1998 (26 pts), honourable mention 1996 (11 pts).Jul 1999
• Onliner 2017 profile: credits school international olympiads for igniting his love of mathematics, and is presented as an emblem of post-Soviet scientific talent emigrating to the US.Aug 18, 2017
• Joined Yale in 2019 straight from a Northeastern full professorship, and holds a concurrent Chief Research fellow role at HSE Moscow's representation-theory lab - a Russia-facing tie maintained alongside his US career.
• Research output is high-volume and collaborative (co-authored with Etingof, Bezrukavnikov, Ostrik, Brundan, Webster, Gorsky), placing him at the centre of the Cherednik-algebra / quantized-symplectic-resolution community rather than on its periphery.
