B.S. Univ of Michigan 1968
M.S. Univ of Idaho 1972
Ph.D. Montana State Univ 1978

In retirement I continue with several writing projects including co-editing a book on barley chemistry and end use to be published by the American Association of Cereal Chemists International. I also collaborate on a couple barley genetics research projects that were in progress when I retired. Read more.
