Søren Galatius (born 1 August 1976) is a Danish mathematician who works as a professor of mathematics at the Columbia University. He works in algebraic topology, where one of his most important results concerns the homology of the automorphisms of free groups.. He is also known for his joint work with Oscar Randal-Williams on moduli spaces of manifolds, comprising several papers.
Life Galatius was born in Randers, Denmark. He earned his PhD from Aarhus University in 2004 under the supervision of Ib Madsen. He then joined the Stanford University faculty, first with a temporary position as a Szegő Assistant Professor and then two years later with a tenure-track position, eventually becoming full professor in 2011.
