If you want to see me on top of an Elephant in Chiangmai, Thailand (with Lou Caccetta) click HERE .
If you want so see me without a beard (as in the elephant photo), then click HERE . A recent photo in the 9th floor lounge of Van Vleck Hall is Right Here Here is a photo of some of those who have served as chairs of the Math Dept and some of its support staff . Photos from Mary Ellen Rudin's 75th birthday party: PHOTO 1 , PHOTO 2 , and PHOTO 3 . If you want to see some photos of me, taken by Brendan McKay at the 4th Shanghai Conference on Combinatorics (May 2002), click HERE , and HERE (with some mathematical grandchildren and mathematical granchildren-to-be), and HERE (a mathematical grandaughter-to-be). Some famous linear algebraists in Auburn in 1980. A picture of the three Brualdi Brothers .
A recent picture with Jose Dias da Silva, taken at the joing India/AMS meeting in Bangalore, India (December 2003) is HERE . A picture of some of the Electronic J. of Combinatorics editors taken at the 2004 combinatorics conference in Lake Taupo, New Zealand (Tank Aldred, Ian Wanless, Brendan McKay. Carsten Thomassen, and RAB). And if you want to see me as a "hippie" in the 1970s, click HERE and in 1973, click HERE.
