Alekseev does research on representation theory of Lie groups and algebras, moment theory, symplectic geometry and mathematical physics.

In 2006 he, with Eckhard Meinrenken, published in Inventiones Mathematicae a proof of the Kashiwara-Vergne conjecture. In 2008 he gave a new proof with Charles Torossian.

In 2014 Alekseev was an invited speaker with talk Three lives of the Gelfand-Zeitlin integrable system at the International Congress of Mathematicians in Seoul.
