Dr. Bauman has a distinguished record of scientific achievement. He is internationally recognized for seminal contributions to the fields of biology and animal science. He has authored over 300 publications dealing with the regulation of nutrient use for pregnancy, lactation, and growth. He was elected to the National Academy of Sciences and served 4 years as chairman of the Board on Agriculture. He is the recipient 13 research awards, and 18 of his students hold positions at academic institutions. Early contributions were in the field of lipid metabolism, where he is noted for his integrated reviews on metabolic regulation. One of his most significant achievements was the concept of homeorrhesis in metabolic regulation. Bauman and Currie published these concepts nearly 20 years ago and they are now used extensively in biology. Bauman hypothesized that somatotropin was a key homeorrhetic control. Its regulatory role in lactation and growth is now well established. His group conducted a substantial portion of the key research that led to commercial use of the first biotechnical product in dairy cattle (bovine somatotropin). His understanding of science and practice and his superb skill as a teacher has made him an effective communicator to scientists, policy makers, producers, and students.
