He was awarded the status of Fellow[1] in the American Physical Society,[2] after he was nominated by the Division of Nuclear Physics in 2009,[3] for contributions to the study of nuclear collisions: the discovery of nuclear orbiting, pioneering measurements of the space-time extent of particle-emitting sources,[4] and seminal studies of fusion with n-rich exotic beams, and for development of innovative instrumentation to enable these studies.
