Based on the postulate that one should change directions every five years to avoid stagnation, my career profile in segments averaging five years starting in 1955 is: (1) graduate school (MIT-PhD): biophysics & fiber diffraction theory, (2) two postdoc positions: x-ray crystallography (Institute for Cancer Research, Philadelphia) & neutron diffraction (Oak Ridge National Laboratory), (3) staff member ORNL until retirement in 1996: thermal motion & computer graphics, (4) crystal physics, (5) artificial intelligence concepts, (6) artificial intelligence applications, (7) machine vision engineering & project management, and (8) crystallographic topology & neutron diffraction.
Post retirement activities involve crystallographic topology, personal computing and enjoying life. A 1997 photograph is shown above. Publications and presentations are listed in a Résumé. Selected professional activities include:
