He obtained his Ph.D. under the guidance of Vladimir Abramovich Rokhlin in 1980 at the Steklov Mathematical Institute.[3]

According to Google Scholar, on 5 July 2020, Ivanov's works had received 2,376 citations and his h-index was 22.[2]

He is a fellow of the American Mathematical Society since 2012.[4]

He is the author of the 1992 book Subgroups of Teichmüller Modular Groups.[5]

Among his contributions to mathematics are his classification of subgroups of surface mapping class groups,[6] and the establishment that surface mapping class groups satisfy the Tits alternative.[7]

gollark: EVIL!
gollark: Actually, that picture of Chorus City is a little outdated, I'll have to see if I can find a better one.
gollark: I prefer Thermal mods, Immersive Engineering is just annoying to work with, especially the multiblocks.
gollark: Oh, here's Chorus City, built on a Minecraft server with basically only ComputerCraft, OpenComputers, Chisel and whatnot.
gollark: Well, not *everything*, but many things.
