Tobias Holck Colding (born 1963) is a Danish mathematician working on geometric analysis, and low-dimensional topology.
In the early stage of his career, Colding did impressive work on manifolds with bounds on Ricci curvature.
[1] He began coauthoring with William P. Minicozzi at this time: first on harmonic functions, later on minimal surfaces, and now on mean curvature flow.
In 2010 Tobias H. Colding received the Oswald Veblen Prize in Geometry together with William Minicozzi II for their work on minimal surfaces.
[2] In justification of the reward the American Mathematical Society wrote: "The 2010 Veblen Prize in Geometry is awarded to Tobias H. Colding and William P. Minicozzi II for their profound work on minimal surfaces.
