Welcome to my webpage. I am a Professor of Mathematical Analysis with the Universidad Complutense de Madrid. In the last few years my research has been focused on smooth approximations and extensions of convex functions.
For instance, is it true that every convex function on  coincides, up to a subset of arbitrarily small measure, with a convex function of class

If you browse through my papers you may find some answers to these questions as well as some information about other related problems.
If you are a student, you may find material pertaining to the classes I teach.
