I grew up in the San Fernando Valley in California, where I earned a
degree in mathematics and then a fifth year single-subject teaching
credential in mathematics. I worked my way through college "busting
tires" at Sears, and in my spare time I taught CPR courses for the
American National Red Cross and I served as a Big Brother of Greater Los
Angeles. I spent the next two years as a Peace Corps Volunteer teaching
mathematics at a junior high school and in a teacher training institute
in Liberia, West Africa, where, while out for a run one afternoon in
the bush, I decided I enjoyed working with prospective teachers even
though I did not know what I was doing. I decided then to pursue a
graduate degree in mathematics education. I returned to the U.S. and
taught mathematics in an inner-city Los Angeles high school and then in
Canyon Country, north of Los Angeles. While teaching, I worked on an
M.S. degree in mathematics at night and I also served on a crisis
intervention help-line. Upon finishing my M.S. degree, I married, moved
to Wisconsin, and studied for my doctorate under the direction of Tom
Carpenter.

I have devoted much of my research and teaching to understanding
and working with prospective and practicing elementary and secondary
mathematics teachers, and to support this work, we have developed video
of children’s mathematical thinking. The CD, which is used in several of
our courses, is available through Pearson/Prentice Hall. Samples of these video are available on our IMAP website (http://www.sci.sdsu.edu/CRMSE/IMAP/video.html).

2013 San Diego State University President's Leadership Fund Faculty and Staff Excellence Award.

A $5,000 stipend for ongoing work was associated with this award.

When I am not working (and even sometimes when I am) our two sons keep my wife and me busy. However, I do make time to work out now and then, and I enjoy backpacking.
