  Nina Uraltseva has made lasting contributions to mathematics with her
pioneering work in various directions in analysis and PDEs and the development
of elegant and sophisticated analytical techniques. She is most renowned for
her early work on linear and quasilinear equations of elliptic and parabolic
type in collaboration with Olga Ladyzhenskaya, which is the category of
classics, but her contributions to the other areas such as degenerate and
geometric equations, variational inequalities, and free boundaries are equally
deep and significant.
  In this article, we give an overview of Nina Uraltseva's work with some
details on selected results.
