Clayton Daniel Mote, Jr. is President of the National Academy of Engineering and Regents Professor at the University of Maryland, College Park. Dr. Mote earned his BS, MS, and PhD degrees at the University of California, Berkeley in mechanical engineering between 1959 and 1963. After a postdoctoral year in England and three years as an assistant professor at the Carnegie Institute of Technology in Pittsburgh, he returned to Berkeley to join the faculty in mechanical engineering for the next 31 years. He and his students investigated the dynamics, stability, and control of high-speed rotating and translating continua (e.g., disks, webs, tapes, and cables) as well as biomechanical problems emanating from snow skiing. He coined the area called “dynamics of axially moving materials” encompassing these systems. Fifty-eight PhD students earned their degrees under his mentorship.
