Professor Frauenfelder repeatedly crosses disciplinary lines, making significant contributions to biochemistry and biological physics, and demonstrates how developments in one scientific field can transform the development of another. He is widely recognized for his contributions to many fields of physics, the structure of surfaces and solids, and space-time symmetries in nuclear and particle physics. He is currently at the Center for Nonlinear Studies at the Los Alamos National Laboratory, where he continues his work on the dynamics and function of biomolecules.
He is the author of several well-known monographs and textbooks. In 1992 he received the Biological Physics Prize of the American Physical Society. He received honorary degrees from the University of Pennsylvania, Technical University of Munich, Stockholm University, and University of Zürich. He is a member of the National Academy of Sciences, American Academy of Arts and Sciences, Academy Leopoldina, American Philosophical Society; and a fellow of the New York Academy of Sciences. In 1999 he was elected a foreign member of the Royal Swedish Academy of Sciences.
