Boris Shapiro (born 1957, Moscow, Soviet Union) is a Russian-Swedish mathematician, whose research concerns differential equations, commutative algebra and Schubert calculus. The Shapiro–Shapiro conjecture (or simply the Shapiro conjecture) was named after Michael Shapiro and him (it is now the well-known Mukhin–Tarasov–Varchenko theorem).
Shapiro enrolled in the Ph.D. program at Moscow State University, Soviet Union in 1985 as a student of Vladimir Arnold, but his thesis defense was rejected by the examining committee. He then defended the same thesis at Stockholm University, Sweden in 1990, and was awarded his Ph.D. Ironically, he became the most prolific Ph.D. student of Arnold, in terms of academic descendance. He has been a professor at Stockholm University since 1993.
