I have a Visiting Reader (Assoc Prof) in the Physics Department at Imperial College, London. I serve on several committees associated with the program of magnetic confinement research, which is increasingly centered in Europe and Japan. I am a Fellow of the American Physical Society. I am currently serving on the American Physical Society's Panel on Public Affairs, which deals with physics issues of national and international significance, including energy, security and education. I am a past Chair of the APS Committee for the International Freedom of Scientists.
