I have been working on supergravity grand unified models with non-universal sof SUSY breaking terms for collider experiments using a Monte-Carlo computer simulation program called ISAJET. The model that I ahve primarliy dealt with is the SO(10) model, which I find of particular interest thanks in part to the easy addition tot he modle of the beutrino mass matrix, the incorporation of thesee-saw mechanism. I would like to explore the SO(10) model in more detail. I would also like to investigate some of the superstring models.
