Special announcements and downloads
I made a page for the photos taken at our Fall 2013 Department Picnic, and another page for the photos taken taken at our end of (academic) year party in 2014. For other one-time events, special downloads, including MATH 1100 information, visit my Special Announcements and Downloads page.
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. I also post dynamically updated versions of my papers on the ArXiv, whenever my coauthors allow it. For published papers you will find a link to the journal. Please email me for an author's copy, if you have no access to the journal. For links to my older papers, try the Publications section of my vita.
