From 1978 he was a member of the Center for Advanced Study, and from 1995 he is a professor emeritus of Physical Chemistry and Biophysics. In 1992 he went to Los Alamos National Laboratory, where he was from 1995 to 2003 director of the Center for Nonlinear Studies. He subsequently Senior Fellow in the Theory Division. 1958/59, 1963 and 1973 he was a scientist at CERN.

In Switzerland, he developed the Perturbed Angular Correlation (PAC ) spectroscopy of gamma -emitters in solids. In the U.S., he moved to nuclear physics, studied parity violation and turned the Mössbauer effect in experiments on. Later he turned to biophysics and the study of proteins.

Since 1975 he is a member of the National Academy of Sciences and the American Philosophical Society, since 1979 a member of the Leopoldina. He is a foreign member of the Royal Swedish Academy of Sciences. In 1992 he received the Max Delbrück Price in Biophysics of the American Physical Society. In 2007 he was awarded the Willis E.
