I am interested in children's cognitive development.  One of the domains I have studied thus far is space.  In particular, I'm interested in children's developing ideas about the relation between two- and three-dimensional space.  In other words, I wish to understand how children internalize three-dimensional space and express it on a two-dimensional medium.

I have a chapter on this topic in the following monograph:
