Research Interests:

• I have been interested in a broad range of fields. My thesis concerned surface physics, even including neutrino recoil. I then discovered perturbed angular correlation (PAC), a field that is still active today. After coming to the US in 1952, I switched to nuclear physics, studied parity violation, and used the Mšssbauer effect to investigate a number of topics. The Mšssbauer effect led to the investigation of biomolecules, in particular proteins. These studies, initially only a sideline, were so interesting that they expanded into a more approach and, today, I am deeply involved in exploring the connections among the structure, dynamics, and function of proteins. My guess is that such studies will form a major branch of physics (Òbiological physicsÓ) for many years to come.
