Research with papers to download

I do a lot of it, especially on all sorts of enumeration problems, and
things related to permutations.

Ok, so after a lot of procrastinating, it is time to upload all my papers here. This will take a while.
I had them all on my old website, but of course, the university changed the system on us.

See My Latest Papers for my most recent papers, which are not published yet.

Sponsors of my research include the Simons Foundation, National Science Foundation , the National Security Agency ,
and the Howard Hughes Medical Institute.
