The 2016--2017 academic year will be my 23rd year at MU. Before coming to MU, I spent twelve years in the Department of Mathematics at Case Western Reserve University in Cleveland.

I was born in Boston, Massachusetts, but I grew up in Honolulu, Hawaii. I graduated from Punahou School in 1972.

(I didn't know Barack Obama; he graduated from Punahou the same year as my younger brother.)

I majored in math at M.I.T. and graduated with a B.S. in Math in 1976. I did my graduate work at Cornell and received a doctorate in math in 1982. My thesis advisor was Kenneth S. Brown.

In math, my primary areas of interest are group cohomology and homological algebra, group theory, and topology. But all math is fun!

Teaching takes up most of my time. I did not become a mathematician in order to teach, but I found out as I did it that I liked it, and that it was very rewarding. I'm interested in the use of technology in education. In the past couple of years, I've experimented with making videos for my classes. I maintain web pages with 500--1000 pages of notes and other math-related materials.

Things I enjoy besides doing and teaching math:

*Working with computers*I use TeX, inkscape, maxima, and emacs lisp to do my work. Linux is my operating system of choice.*Strength training*I use soloflex and free weights. I ran regularly for 30 years, but stopped after hurting my knee. Now I do fast walking and stationary bike.*Reading*I love books, and have had to force myself to stop buying books because I have limited time to read. I recently finished Daniel Kahneman's "Thinking Fast and Slow" and Robert Richardson's biographies of Thoreau and Emerson (all of which were wonderful). I usually have bookmarks in ten or twenty books (aside from math books).*Gardening*I used to hate yard work when I was a kid. Now it seems really rewarding, and it's good exercise. I have tons of stuff in my yard, and a small vegetable garden.*zazen*I began learning about Buddhism in an asian history class in 11th grade. I've had a Buddhist meditation practice since around 1999.
