Information for my colleagues
I have a separate Professional Information page, containing (among others) links to: my vita, description of my past research, and homepages of (pre-UNCC) classes I taught.

The original version of my most recent papers may be found in our departmental Preprint Archive. Below you will also find a link to the latest version. This second link is local only if the paper has not yet appeared. For links to my older papers, try the Publications section of my vita.
