http://www.math.ucr.edu/home/baez/thesis_wise.pdf Derek has taken a position at UC Davis and been moving his webpages up there from UC Riverside. John Baez has discussed a chunk of Derek's research in a paper he delivered at a conference a few months back. Also Derek has summarized part of it in a paper he put on arxiv last year. http://arxiv.org/abs/gr-qc/0611154 Cartan geometry could turn out to play a crucial role in quantum gravity. Derek is a good clear writer so his earlier paper was a pleasure to read (the one everybody remembers as having the hamster in a ball rolling over a differentiable manifold). Here is Derek's new UCD webpage http://www.math.ucdavis.edu/~derek/ I've looked thru the thesis and see that one useful thing it does is gather several related lines of investigation into one organized exposition. I suspect several of us have already read large portions of Wise's thesis in other formats (I certainly have, with interest!). A good deal of the content had already been made public in papers and online slides.
