Why was he wearing a mask?
I'm also a charter member of the Atlas of Lie Groups Project, whose goals are to understand, classify, and catalogue the representations of semisimple real and p-adic Lie groups. A surprising amount of the work we are doing involves challenging combinatorial and computational problems--that's why I'm involved.
I maintain an archive of my recent papers and a publication list.
I also have an archive of other papers (i.e., papers not intended for publication).
Here's a nifty example that was created with the posets and coxeter packages.
By popular demand, I also have created an archive of Research Data And Other Useful Stuff. To whet your appetite, here's a sample of the cool stuff you can find there:
A projection of the nearest neighbor graph of the E6 root system into its Coxeter plane.
