I will describe our recent classification of noncollapsed singularity models for the mean curvature flow of 3-dimensional hypersurfaces in R^4 or more generally in 4-manifolds. Specifically, we show that every noncollapsed translating hypersurface in R^4 is either R×2d-bowl, or a 3d round bowl, or belongs to the one-parameter family of 3d oval bowls constructed by Hoffman-Ilmanen-Martin-White. This is joint work with Choi and Hershkovits.
