I really wish I had the chance to take algebraic geometry as an undergraduate, but there is no course in the subject at my university (we have one algebraic geometer, and he has given it as a grad course before).
My strongest interest is in general topology, but this isn't really an active research area anymore. My other main interests are set theory, and applications of set theory to other areas (especially topology and analysis). I'm hoping to end up doing some kind of set-theoretic topology, but it depends which grad schools accept me. Topological groups, functional analysis, as well as mathematical logic, are also topics I find increasingly interesting.
