Biography
Received his Diploma in Physics in 1989, and a Ph.D. "summa cum laude" in 1991, from the University of Mainz, Germany, working with H. W. Spiess at the Max-Planck Institute for Polymer Research. In 1992, he was a staff scientist at the Max-Planck Institute and wrote a book on "Multidimensional Solid-State NMR and Polymers" (with H. W. Spiess). He then spent two years in the group of Alex Pines at UC Berkeley, as a postdoctoral fellow of the BASF AG and the German National Scholarship Foundation. In 1995, he joined the Department of Polymer Science & Engineering of the University of Massachusetts at Amherst, where in 1997 he was promoted to Associate Professor. He was a professor at Iowa State University from 2000-2014. He joined the faculty at Brandeis University in 2014. In 1996, he received the Rudolf-Kaiser Prize from the German Physical Society, and a Beckman Young Investigator Award from the Arnold and Mabel Beckman Foundation. In 2000, he was awarded an Alfred P. Sloan Research Fellowship, in 2001, the John H. Dillon Medal of the Polymer Division of the American Physical Society.
