Some Places I've been
I've lectured alphabetically from Aalborg (Denmark) to Zomba (Malawi) and north - south from Torshavn (Faeroe Islands) to Hobart (Tasmania) as well as in London, Paris, Amsterdam; Budapest, Shanghai, Xi'an, Jinan, Hakone; Toronto, Sydney, Auckland, etc. I've visited departments or companies in Kiev and Odessa, Ukraine, and Delhi, India.
My wife and I are active in Servas, a peace organization encouraging international home-to-home visits. Among other organizations, we have traveled with Elderhostel and Global Volunteers, the Foundation for International Community Assistance and the American Indian College Fund. We've been camp counselors (English tutors) at a children's camp in rural Eastern Poland and visited small colleges on Indian reservations.
We are happy to provide some of our charity-related travel pictures; many have pointers elsewhere on the ordman.net pages.
I migrate between Tennessee and New Hampshire
(works at both homes)
(Secretary at Dept. of Math Sciences, U of Memphis, 901-678-2482,
generally knows where I am.)
Most Recent Projects
(This was true when I retired in 2001. As of 2018, I'm
mainly an interfaith activist.)

Something my mother noticed
The University of Memphis does a very good job with students who have handicaps. I very much like advising students. In late 1997 Ann Landers included a letter about my work with handicapped students. While no one has ever called my mother to mention seeing any of my 40 or 50 professional papers, 15 people called my mother that morning before breakfast. Since then, in my mother's eyes, I am a success. For more about this, click here.
