Personally, I've always found comparative genomics to be of particular interest. It has lots of applications and produces a variety of results.
For example, there is the biological trend known as 'clastistics'. In the past, animals were grouped with each other on rather coarse assumptions of similarity and what may have led to what. But by using genetic analysis these days, many biologists are asserting that some of the old categories into which animals have been grouped are just wrong. In some cases, things seemingly distantly related are shown to have very similar DNA, and in others convergent evolution has brought totally seperate species to very similar points. Were it not for our growing understanding of genomics, many of these associations might never have been known.
Another fascinating development from comparative genomics is in immunology. Here we can put some of the unusual associations discovered to practical use! Sometimes, where a disease, drug, or illness targets or is the result of genetic heritage, it becomes very useful not only to examine how these factors interact with other creatures with similar or identical genes, but also to see how those animals may have overcome things which are obstacles to us. For example, if we find that a snail has the exact same marker that we do and which serves as a target for a virus, we may discover not only a good way to study that disease in snails instead of people, but also a way to defeat it, if the snails have a natural defese! Yay genomics!
Anyway, that's a couple ideas, at least. I'm sure there's many more! Have fun with it!
