What vitamin is David P. Ballou known for studying?
David Ballou David P. Ballou is a professor of biological chemistry at the University of Michigan Medical School in the United States. He is best known for his development of rapid-reaction techniques, including stopped flow and rapid freeze-quench EPR methods, as tools to study the mechanisms of enzymes containing flavin, iron, cobalamin, or pyridoxal phosphate cofactors. Many of these studies were performed in collaboration with other scientists, most often with colleagues at Michigan.
Edwin N. Lightfoot Lightfoot received his B.S. and Ph.D. degrees in Chemical Engineering from Cornell University. After graduate school he worked for Pfizer & Co in Brooklyn where he received US Patent US2787578 A for his development of a commercial process for recovering and purifying vitamin B12. He began his teaching career at the University of Wisconsin-Madison and later became a Professor of Chemical and Biological Engineering. Currently he is the Hilldale Professor Emeritus in the Department. His research interest are in the development of improved separation processes and controlling the dynamics of biological systems.
