This photo was taken by Olle Swartling at 4:50 p.m. on July 25, 1969, from the summit of Nevado Chinchey, 20,413', in the Cordillera Blanca, Peru. I'm on the left; Steve Moore is on the right.

My research interests are in commutative algebra and representation theory.
Graham Leuschke's and my book Cohen-Macaulay Representations appeared in 2012, in the American Mathematical Society's Surveys and Monographs series.
(P)reprints of some of my PAPERS are available, along with errata and commentary for the conscientious reader.


I enjoy rock climbing and mountaineering (as you might guess from the photo). Check out some more pictures taken on an ascent of the Longs Peak Diamond during the summer of 2000. And here are some more recent pictures of some climbing in Provence, in March, 2009. Back in my youth I did a few 100-mile trail runs. One such adventure was the 1999 Hardrock Endurance Run
